At 24" cuff height, this is a true compression sock which offers muscle support clear up your calf. The Active 24 sock has a good balance of solid muscle compression without the stranglehold of most compression wear. Since the folks at Capo got their start in the sock business, this item was kind of a no-brainer for them and has all the features you'd expect from a Capo sock. The construction of the garment comes from 200-needle high gauge Olefin. This comes of no surprise seeing that Olefin is a widely used fabric by Capo designers due to its durability, comfort and wicking capacity. Choose size and color.
