They seem to run big
I have an old pair of Salomon F22s that I have boarded in for years. I LOVE them. I got this new pair in the same size but they're too big and they give me blisters on my heels. I guess models change from year to year. Note also that although the dogfunk site says they have a removable liner they don't. It's sewn in. I am not sure why it says they're removable. I have never been able to get them out.
