" Designed for maximum comfort with todays technical approach footwear. The 100% Tactel inner layer stays with the foot, wicking away moisture, whilst the soft wool/nylon mix outer moves with the shoe. The unique combination of fibres maintains a comfortable temperature for the foot. Heres what boxing professional Anthony Ogogo says about the socklets: " These socks are brilliant. As a boxer I spent a lot of my time pounding the road to gain stamina & fitness. However we also spend a lot of our time up on our toes when we are training. In the past Ive often got quite painful blisters on my toes & the balls of my feet. However wearing these they really help the foot move nicely in my boxing boots & I havent had a painful blister since wearing these. A blister sounds trivial but can be a real pain & affect my training routine so I make sure I always wear my 1000 mile socks whilst Im in training camp." Suitable for 2 season walking. Inner Layer: 100% Tactel Outer Layer: 66% Merino Wool, 35% Nylon, 1% Lycra"
