A superb sock with a very high Cool Max content to ensure maximum dryness, protection and comfort. Ideal for multipsort exertion including running and cycling. This is the very same sock supplied to all competitors competing in the 170 mile, 6-day Britvic Marathon of Britain and praised by all. The toe and heel area are padded for impact protection, as is the ankle area, for protection of the achillies tendon. An elasticated instep and 'Lin toe' toe seam help reduce movement of the sock and rubbing to prevent blisters.
