Aрpellant, Brooks Shoe Manufacturing Co., Inc. (“Brooks”) brought this action for trade dress infringement against Suave Shoe Corporation (“Suave”). After a non-jury trial, the District Court for the Southern District of Florida entered judgment in favor of Suave. We affirm.
I. FACTS 1
Brooks is a Pennsylvania corporation which has been selling athletic shoes and related products since 1914. 2 Most of the shoes Brooks sells are “high performance” shoes, made of lightweight, durable, high-quality materials and dеsigned to meet the needs of serious athletes. The majority of Brooks’ sales are to stores which sell a full line of sporting goods or stores which specialize in selling athletic shoes. In 1978, Brooks shoes generally sold at retail prices in excess of $25 per pair.
In 1973, Brooks began selling shoes with a “V” design on the sides. By 1977, this “V” design appeared on almost every shoe in the Brooks line. In the late 1970’s, Brooks engaged in substantial promotional activities, advertising its shoеs in magazines such as “Runner’s World” and “Running Times,” sponsoring races and other athletic events, and paying various professional athletes to wear Brooks shoes. During this same period of time, the sales of Brooks shoes increased rapidly. 3
Suave, a Florida corporation, is primarily engaged in manufacturing and selling casual, athletic, work, dress and leisure shoes. Traditionally, Suave has been a major manufacturer of canvas shoes. In response tо changing consumer preferences in the mid-1970’s, however, Suave began manufacturing athletic and leisure shoes with vinyl, man-made suede and nylon uppers. Suave sells most of its shoes to mass merchandisers, variety stores, drug stores, and discount stores. Generally, Suave shoes are unbranded or carry the retailer’s brand name. Suave shoes are made of inexpensive materials, and in 1978 Suave shoes generally sold at retail prices ranging from $8 to $12.
In January of 1979, Suavе began manufacturing and selling a line of athletic and leisure shoes which had a “V” design on the sides. 4 Brooks, through its attorney, promptly notified Suave that it believed that the use of the “V” design infringed on Brooks’ trademark and trade dress rights. When Suave did not immediately discontinue production of shoes with the “V” design, 5 Brooks brought an action in the district court alleging violations of § 43(a) of the Lanham Act, 15 U.S.C. § 1125(a), the Florida Deceptive and Unfair Trade Practices Act, the Florida Anti-Dilution Stаtute, and the common law of unfair competition. The district court refused to grant a prelim *857 iuary injunction and, after a six-day non-jury trial, entered judgment for Suave on all counts. On appeal, Brooks contends that the district court erred in entering judgment for Suave on the Lanham Act claim. 6
II. DISCUSSION
In order to prevail on a trade dress infringement claim under § 43(a) of the Lanham Act, a plaintiff must prove that its trade dress has acquired secondary meaning,
7
that features of its trade dress are primarily nonfunctional, and that the defendant’s product has trade dress which is confusingly similar to its own trade dress.
See John H. Harland Co. v. Clarke Checks, Inc.,
Brooks’ first contention is that it did not have to prove secondary meaning because its “V” design is inherently distinctive. Brooks points out that the former Fifth Circuit’s decision in
Chevron Chemical Co. v. Voluntary Purchasing Groups,
The difficulty with Brooks’ argument is that the district court assumed that a plaintiff need not prove secondary meaning whеn its trade dress is inherently distinctive, but found, as a matter of
fact,
that “there is nothing arbitrary or fanciful about the Brooks’ ‘V’ that would make it inherently distinctive.”
In
Seabrook Foods, Inc. v. Bar-Well Foods, Ltd.,
In this case, each of these factors indicates that Brooks’ trade dress is not inherently distinctive. As the district court noted, the design on the sides of Brooks shoes “could be characterized as a ‘V’ on its side, an arrow, or a ‘7’.”
Further, although Brooks relies heavily on the former Fifth Circuit’s decision in
Chevron Chemical, supra,
to support its contention that the “V” design is inherently distinctive, examination of the facts of that case indicates that Brooks’ reliance is misplaced. The trade dress which the court found was inherently distinctive in
Chevron Chemical
involved “the combination of particular hues of colors, arranged in certain geometric designs, presented in conjunction with a particular style of printing, in such fashion that, taken together, they create a distinctive visual impression."
Brooks’ second contention on appeal is that it did not have to prove secondary meaning because the district court found that Suave “intentionally copied the ‘V’ design and the color schemes used by Brooks
*859
and other shoe manufacturers.”
We recognize that some courts have indicated that proof of certain egregious conduct by a defendant, such as palming off,
11
is sufficient to establish secondary meaning.
See
1 J.T. McCarthy,
supra,
§§ 15:4-5 (discussing cases which have allowed substitutes for secondary meaning). In most cases, however, the court indicated that the plaintiff had to prove more than just intentional copying in order to be relieved of the burden of proving secondary meaning. For example, in
Polo Fashions, Inc. v. Extra Special Products, Inc.,
In this case, although the district court found that Suave had intentionally copied Brooks’ design, the court also found that Suave had not engaged in palming off or actual deception.
Brooks has not cited any cases from this circuit or from the former Fifth Circuit which hold that proof of intentional copying alone eliminates the need for proof of secondary meaning,
13
and we decline to
*860
adopt such a rule in this case. Although we believe that рroof of intentional copying is probative evidence on the secondary meaning issue, we cannot agree with Brooks that proof of intentional copying conclusively establishes that the plaintiff’s trademark or trade dress has acquired secondary meaning. As Professor McCarthy has noted, close copying does not
necessarily
indicate that the defendant has attempted to capitalize on the secondary meaning of plaintiff’s trademark or trade dress because “[t]here may have been many other motivations for defendant’s actions.” 1 J.T. McCarthy,
supra,
§ 15:4, at 531. Further, “[i]t must ... not be forgotten that there is absolutely nothing legally or morally reprehensible about exact copying of things in the public domain.”
Id. Cf. B.H. Bunn Co. v. AAA Replacement Parts Co.,
Brooks’ final contention on appeal is that the district court erred when it found that Brooks had not established that its “V” design had acquired secondary meaning as of January 1979. Whether a particular trademark or trade dress has acquired secondary meaning is a question of fact,
Volkswagenwerk Aktiengesellschaft v. Rickard,
In an effort to prove that the “V” design had acquired secondary meaning as of January 1979, Brooks presented evidence of a substantial increase in sales during the late 1970’s which Brooks attributed to its promotional efforts. We recognize that evidence of sales, advertising and promotional activities may be relevant to determining whether a trademark or trade dress has acquired secondary meaning, see 1 J.T. McCarthy,
supra,
§§ 15:16-19, but we are unable to conclude that Brooks’ evidence was sufficient to prove secondary meaning in this case. As the district court pointed out, the growth in Brooks’ sales during the late 1970’s may have been attributable in large part to the increased interest in running and jogging during the same period.
14
More importantly, the district court found that much of Brooks’ advertising featured the “mechanical and design aspects of [Brooks’] shoes,”
Brooks also relied on a consumer survеy to prove that the “V” design had acquired secondary meaning. The district court admitted the survey into evidence, but did not give it much weight because the survey contained numerous “procedural and methodological errors” and, even more important, was not based on a proper survey universe.
Brooks has not cited any other significant factors on the secondary meaning issue. 17 *862 Accordingly, we hold that the district court did not err when it concluded that Brooks’ “V” design had not acquired secondary meaning as of January 1979.
The judgment of the district court is AFFIRMED.
Notes
. We briefly summarize the facts as found by the district court.
See Brooks Shoe Manufacturing Co. v. Suave Shoe Corp.,
. Despite its name, Brooks does not actually manufacture the shoes that it sells.
. For example, sales of Brooks training shoes increased from slightly over 400,000 in fiscal 1976 to more than 2,500,000 in fiscal 1978. Brooks attributed this rise in sales to its promotional efforts, but the district court noted that the increased interest in running as a form of exercise during the late 1970’s may have contributed significantly to the rise in sales.
. Suave’s counsel has consistently argued that Suave’s shoes have a “7” design rather than a “V” design. We do not attach any importance to this alleged distinction between the designs.
. Although Suave did not discontinue production of shoes with the “V” design immediately, the district court found that Suave voluntarily stopped producing such shoes shortly after receiving a letter from Brooks’ attorney.
. Brooks has not appealed the adverse judgment on the Florida law and common law claims.
. To establish secondary meaning the plaintiff must show that the primary significance of the product in the minds of the consuming public is not the product itself but the producer.
See Vision Center v. Opticks, Inc.,
. The district court also found that there was no likelihood of confusion between the trade dress of Suave’s shoes and the trade dress of Brooks’ shoes. We need not review this finding because we conclude below that there is no error in the district court’s ruling on the secondary meaning issue.
. As noted in
Original Appalachian Art Works, Inc. v. Toy Loft, Inc.,
. Recent opinions by the Trademark Trials and Appeals Board have noted that there are numerous athletic shoes in the marketplace which contain decorative stripes, bars and designs.
See In re Lucky Co.,
. “Palming off is an attempt by one person to induce consumers to believe that his product is actually that of another; it requires an intent to deceive and proof of actual fraud.”
Ralston Purina Co. v. Thomas J. Lipton, Inc.,
. We expressly do not decide whether proof of some other type of conduct by a defendant might be an adequate substitute for proof of secondary meaning.
. In its brief, Brooks relies heavily on a former Fifth Circuit case which dealt primarily with the analogous likelihood of confusion issue and stated that “if ... a plaintiff can show that a defendant adopted a mark with the intent of deriving benefit from the reputation of the plaintiff, that fact alone ‘may be sufficient to justify the inference that there is confusing similarity.’ ”
Exxon Corp. v. Texas Motor Exchange, Inc.,
. John E. Overlock, a consultant and the former chairman of the Athletic Shoe Committee of the Sporting Goods Manufacturers Association, testified at trial that overall sales of running shoes almost tripled between 1976 and 1979.
. The district court opinion fully discusses the problems with the survey,
. In addition to discounting the value of Brooks’ survey, the district court gave considerable weight to survey evidence introduced by Suave.
See
First, Brooks argues that Suave’s survey had numerous procedural and methodological errors. Our review of the record indicates that while Suave’s survey had deficiencies, the district court did not err when it concluded that the survey “substantially complie[d]” with the factors listed for evaluating consumer surveys in the Handbook of Recommended Procedures for the Trial of Protracted Cases which was issued by the Judicial Conference of the United States in 1960.

Second, Brooks contends that the district court should have excluded the testimony of Suave’s survey expert due tо an alleged conflict of interest. The record reveals that Brooks contacted the expert in January of 1980 regarding the possibility of conducting a survey for Brooks. After an exchange of letters, Brooks’ representatives had one meeting with the expert, but decided not to hire him. Shortly thereafter, Suave’s counsel, who was unaware of the expert’s meeting with Brooks, hired the expert to conduct Suave’s survey. Brooks learned that Suave had rеtained the expert in April of 1980, but did not file a motion to disqualify the expert until December 19, 1980, only a month before the trial. The district court conducted a hearing on the motion to disqualify, found that Brooks had never actually retained the expert and that there was no merit to Brooks’ allegation that the expert had received confidential information, and thus ruled that the alleged conflict of interest should not prevent the expert from “testifying as to facts that are based on his education and experience and his conclusions based on those facts.” Record on Appeal, vol. 3, at 779. Under the particular circumstances of this case, we find no error in the district court’s ruling.
. As noted in the text accompanying notes 11-13,
supra,
the district court’s finding that Suave intentionally copied Brooks’ “V” design is evidence on the secondary meaning issue. However, the weight to be accorded this evidence is lessened considerably by the fact that the district court also found that “the ‘V’ design and color schemes were fashionable and ... did not constitute a representation as to the origin of the shoes ... [and that] there is no proof that the Defendant intended to derive benefit from the
reputation
of the Plaintiff.”
Brooks also argues that the Patent and Trademark Office has determined that Brooks’ “V” design has acquired secondary meaning and “is prepared to give final approval to [Brooks’] trademark application” as soon as Brooks files a consent agreement signed by Bata Shoe Company, which registered a similar design in 1971. Reply Brief for Plaintiff-Appellant at 11 (citing letter from U.S. Patent and Trademark Office, July 30, 1981). Aside from the fact that it is based on non-record evidence, Brooks’ argument is not persuasive. Even if *862 the Patent and Trademark Office ultimately determines that Brooks’ “V” design has acquired secondary meaning and registers the mark, that would not indicate that the design had acquired secondary meaning as of January 1979, the time period which is relevant for this case.
