The CEP Progressive Compression Running Socks blend the comfort of a running sock with the benefits of compression sleeves. Graduated compression promotes blood return and flow, enhancing circulation to stressed muscles. This improves nutrient delivery and speeds recovery time. These socks also have padding through the foot for comfort, flat seams to prevent pressure points and chafing, and an anti-microbial treatment to reduce odor buildup. If you have shin splints, cramping, or just general muscle pain during a run, you'll want to give the CEP Progressive Socks a try.
