I usually wear 10/11 and the 10/11 size is working great for me! We both have flat feet. Not worried about durability as there?s 20 pairs for such a fair price and could toss it and pull out a new one if worn out. In a nut shell they probably would be best for a teen or female with thin legs. Overall, they are very convenient. Mids: Relatively missing, as with V-Shaped. It took almost an hour an a few bad words. This is my 4th pair of this model from Head. Chegou tudo ok, mas a caixa não veio lacrada. I find there is one flaw that could be easily overcome.
