I purchased these for a trip to Disneyland in hopes of not getting blisters and it was successful! I wear a size 8-8.5 shoe and another reviewer suggested to go up a size on these socks to a Medium instead of Small for a less tight fit and that was great advice. The socks are very comfortable and did prevent blisters!

I initially ordered a pair of Balega blister resist light socks for my son who runs a lot including marathons. I knew he loved the brand, but I had never seen that particular sock. I also ordered a couple of other pairs for myself and my daughter-in-law. When I saw how truly light the socks were, I put them in my drawer and wrapped a pair of Ultraglides for my son. I thought they looked too thin to be effective over a distance. However, after wearing them I realized I may have made a mistake. I don't know about marathons, but they are wonderful for my daily activities. I'm so glad I tried them by mistake! They are comfortable and durable. I love that they put mohair and wool in a light sock. They make my feet happy!

My cross country and distance track son swears by them. His feet are happy.
