Sales of basketball footwear are continuing to grow, according to recent research, with the kids' segment driving double-digit gains.

Total basketball footwear retail sales in 2013 reached $3.3bn, a 19% increase over 2012, data released last week by global information company The NPD Group shows. This includes the categories of performance, sports lifestyle, and classic basketball shoes.

Total sales for women's basketball footwear declined 15%, while men's increased 17%, and kids' jumped 26%.

The upward trend in basketball footwear sales continued in the first two months of 2014, with total sales increasing 21% in dollar terms to $685.1m compared to the same time period last year.

Again, the kids' segment scored high points, driving the current growth with a surge of 45% to $286m, with men's following in second place, rising 8% to $394.8m. But sales of women's basketball footwear declined 21% to $4.3m in the two-month period.

"With the spotlight on basketball around this time of year due to the NBA All-Star Game leading up to the NCAA Tournament, January and February are key months for basketball footwear retailers to launch their new styles," said Marshal Cohen, NPD Group chief industry analyst.

"Along with the already expected healthy momentum, some popular new launches drove sales up even further this year."

The top three cities for total basketball footwear revenue in 2013 were New York, Chicago, and Los Angeles, with Atlanta being the fastest growing out of the top 10 basketball U.S. footwear markets.

"The secondary markets are where the basketball shoe action is. The passion of the younger consumer reaching for basketball shoes has shifted away from the big city markets to more rural areas, driving the growth as the business goes mainstream," states Cohen.
