This is the 15″ length DaviShins Leg Guards:
Here is another major step forward in umpire comfort, protection and fit from Gerry Davis Sports and Wilson Sporting Goods. This new concept in shin guards is built with a hinge-style flexibility that actually wraps around your leg.
It has recessed, no-gap kneecap protection, and has the two-strap mount system. In addition, there are a series of three optional-mount ankle guards to protect the top and side of your foot. They mount with Velcro®, so you can use one, two or all three of the guards depending on the shoes you wear behind the plate. Sizes are 15” or 17.5” length.
