Only an expert on myself, after 5 ankle operations, but I would assume you would still be using crutches that soon after being non weight bearing. Depending on how much weight you can put on it you may need a built up heel put into the plaster or just a walking shoe, which they will give you. Non weight bearing is such a bitch isn't it. After my last operation I was non weight bearing for 5 months and then had to have the built up heel for 2 months before being taken out of plaster.
