Purchased socks from Grip6 on friend's reccomendation, but he forgot to tell me about the size PROBLEM. He wears a size 8, according to the chart 7.5-9.5 is Medium, being in the middle he ordered Medium. Sent them back for Large because they were Too Small and got Large. Better but still tight. Well I wear size 13, chart says 12.5-14 is X-Large so I ordered those. GREAT Socks but TOO SMALL. So I gave 6 pairs to my friend, size 8 but X-Large is the CORRECT FIT, and I am still Looking for Socks... Short version, Great Socks but order TWO Sizes bigger than the Size Chart says.
