Compressport TRAINING SOCKS 2-PACK. They are suitable for any sport activity. A wide, ergonomically shaped toe, a special textile band to support the instep, 3D protrusions and multi-compression fibres provide you with support and comfort during sports. 3D protrusions also ensure impact absorption thanks to their extraordinary technology and enable air flow around the foot. The protrusions do not retain moisture, thus your foot remains dry. 3D protrusions can also be found in the back, along the Achilles. There, they have a massage effect.
