I recently purchased my first order from Grip6...two pair of their "Fastback Wool Ankle Socks" and two pairs of their "Approach XT Wool Ankle Socks". After wearing these exclusively for the past few weeks, I really like both styles which have been comfortable during all my summer activities, keeping my feet cool as I've spent a lot of time outdoors in the steamy Kansas June and July weather. The cushioning feels good too. Time will tell on their longevity, but so far so good. I've just ordered another 2 pair of each to keep me out of the laundry room so often.
