I love these boots. They are very warm and water proff. I knew jambu shoes run big. I usually take a 10 and ordered a 9.5. They still seemed too big. I went to a local store that carries them and tried on a 9. I should of got a 9. Since I work in the cold I kept the 9.5 and wear 2 pairs of socks. The inside is almost like velvet but it is still easy to get them on and off.
