More explosive starts and stronger strides The Supreme Pro Sock is slightly thicker with incredible compression. It has a small lift in both the heel and the toe. This promotes more explosive starts, stronger strides and locks the foot into the boot better. Keep your feet dry and comfortable Features Merino Wool to transport sweat and moisture away from the skin so you're not left feeling wet, cold, and clammy during your skate. We’ve blended this with synthetic fibers so you can still get the feel and durability of our traditional pro sock. Comfort and support Features an anatomical left and right fit as well as compression arch support. There is also extra padding where the tendon guard touches the foot for added comfort.
