Consequently, these ladies twin packed Storm Bloc with BlueGuard Wool Blend Socks are very capable indeed; 30 times more durable than standard walking socks, temperature managing with natural wool and cotton, and protective with positioned cushioning, extended heels and woven arch supports. Reinforced toe seams contribute further to the inherent strength of these outstanding hike socks. Such is our confidence in the durability of Storm Bloc socks that they come with a lifetime guarantee against developing holes during wear.
