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 Under Armour CompFit. The form-fitting sleeve was praised by Sneaker Report's review team for its lockdown benefits in the UA Cam Highlight Trainer. Since then, UA has added CompFit to everything from lacrosse to running shoes, in both high and low cuts.
What is it? A supportive ankle sleeve constructed of neoprene. Models such as the FTHR Shield TRC Storm and Highlight Trainer/Lacrosse feature a higher cut sleeve, while the Nitro Diablo MC and Nitro III are trimmed down but offer similar lockdown support.
How does it work? By snugly wrapping around the ankle, CompFit offers a number of benefits. The soft neoprene is comfortable and plush, and the supportive sleeve helps to keep the foot in place. By locking down the foot with a custom fit, CompFit allows the sneaker to perform quicker and more efficiently.
Bottom Line: If heel slippage has ever been an issue for you, CompFit may be the solution. Supportive and lightweight, CompFit is featured on sneakers suitable for nearly every sport.
