KNOW YOUR TECH breaks down the scientific technology used in your favorite sneakers and activewear. Let’s demystify your next purchase: today’s technology is Spalding D30 cushioning. Spalding has had an interesting path in the world of basketball footwear. Of course, the brand is well known for manufacturing the official NBA game balls and other gear, but their presence in footwear has been sporadic throughout the years. In the '90s, they laced legendary players like Hakeem Olajuwon in signature styles, however they appeared to have fallen off the sneaker radar as the 2000s came along. In recent years, they've made an exciting comeback, outfitting pro players like Jimmer Fredette and Mario Chalmers in their signature styles. Spalding D30 is the cushioning behind two of their most recent models, the Threat and Slash. While it remains to be seen if D30 is used in the upcoming Spalding Cytek model, it's become the brand's standard impact protection.

What is it? Spalding D30 is a relatively standard foam cushioning setup which is paired with EVA foam in the midsole of the brand's basketball sneakers. Reviewers have compared the on-court feel of Spalding D30 to that of Under Armour's Micro G.

How does it work? Spalding D30 is a relatively simple setup, making use of sturdy yet soft and responsive foam that absorbs shock as players run and jump on the court.

Notable products: Spalding Threat, Spalding Slash

Bottom line: Let's not beat around the bush—Spalding D30 isn't groundbreaking by any means. However, it delivers reliable on-court cushioning and protection at a fraction of the price of other brand's top models.
