The Pro Wrap Liner is the Power Wrap on a wee diet, so you don’t have to be. Its medium-volume thickness and reinforced cuff provide the same reliable stiffness, but with a 2 mm Strobel sole and 7 mm removable foam insole you can easily adjust volume. Perfect for custom footbeds, high arches and wide forefeet. Particularly right after Thanksgiving when your feet are at their fattest.
