I normally wear a size 10 and these were a great fit.  At 500 gm (17.6 oz), they only weigh 2/3 as much as the New Balance gym shoes they're replacing.  At the same time, there is a lot more resilience and cushion when walking or running; perfect for the gym which is why I bought them. They give good support and are a great value at about half what I paid for the New Balance several years ago.  I'm glad I found them on Amazon !
