But Birkenstocks (many of which are sandals) DO have an amazing amount of support. Naots too have support; they have heel cushioning as well. For myself, I have tried changing shoes during the day; sometimes it works okay, sometimes it doesn't. Right now, Birks are working the best of anything -- I don't walk around a lot, but the walking and standing that I do have to do, I CAN do fairly easily. Glad to hear your surgery went well; hope it continue and that you have full relief soon.
