"I wear a size 9 1/2 wide. These did not come in wide so I originally got a size 10. When I got the boots and tried them on, they were very tight so I immediately returned them and exchanged them for a size 11. About a week later I got the size 11 just in time for our first snowfall. The larger size fit perfect, the boots kept my feet warm and dry. BE SURE TO GET THESE IN A LARGER SIZE! The $20 savings was great too."
