It borrows the recessed, no-gap kneecap protection we've offered for years and continues our own two-strap mount system. You know you really don't need a strap behind your knee! In addition, we've developed a series of three optional-mount ankle guards to protect the top and side of your foot. They mount with VelcroÂ®, so you can use one, two or all three of the guards depending on the shoes you wear behind the plate. Black only with subdued Wilson and DaviShins logos. Choose either the 15" length or the 17.5" length.
