I think Madison is the only one who has it and they are not sharingI think they do run big on me and I sized down a full size. but you can adjust the strap on the heel to make it tighter so your foot doesn't slide around. Can your SA do a charge send or transfer from another store so you can at least try them on?

I am hoping this will be in regular collection going forward and I will get one eventually. Thank you for sharing your experience. It sounds like 40 will be huge.
