Just got the Crispi Guide Non-insulated from a local dealer. I tried my normal size, but they weren't quite right so the sales guy suggested that I should try sizing up & adding some Super Feet insoles. I was a bit skeptical at first but was blown away at how much of a difference they made. I've had surgery on both feet, so I am prone to sore feet fairly quickly, but this has been a game changer for me. I highly recommend, but would definitely try them on first before buying as every boot fits differently. Good luck!
