L.E.K. Consulting’s Footwear and Apparel Brand Heat Index, now in its second year, helps brands and retailers identify which brands are gaining popularity across different generations of consumers. In a survey of nearly 4,000 U.S. consumers between the ages of 14 and 55, hundreds of footwear and apparel brands were evaluated by product category (athletic, casual, outdoor and dress), gender and generational cohort, namely, Generation Z, millennials and Generation X. Brands were then assigned a heat score based on their gains in popularity (i.e., their brand heat), expressed on a scale of 0-100. The higher the score, the hotter the brand. It’s important to note that the Brand Heat Index identifies brands on the most positive growth trajectory with shoppers, not necessarily their relative size or scale. Among all the brands evaluated, this report looks at the top 10 brands in each of 16 segments.
At a high level, a number of notable trends were observed in the 2023 Brand Heat Index. For example, while many of the top apparel brands vary depending on the gender of the consumer, some leading players are effectively serving both markets, especially in the athletic and outdoor categories, e.g., lululemon, Gymshark, The North Face and Patagonia.
