This is a Protection Level 2™ running product designed for those who prefer a moderately thick product. If this product does not give your feet the protection you require, you need to choose a Protection Level 3™ product, which provides the most protection available today and requires a proper shoe fit.

Features:

1) Midweight padding in the ball and heel provides better durability and protection against shock, impact and shear forces.
2) Lightweight padding in arch for better fit and arch support.
3) Flat knit stretch nylon at instep for less bulk and ultimate fit.
