Any good sturdy shoe that you can put on and off without having to touch it is great. I wore my moccasin type slippers for almost three months, even when I went out someplace, until I finally bit the bullet and went to the shoe store with my grabber. I dropped shoes that looked possible onto the floor. If I could put it on, walk comfortably in it, and get it back off without ever having to lean over, it was a candidate. The ones I got are still my favorites now, two+ years later. No ties, no velcro, just slip on, but not too loose. If you can get them ahead of time, that would be much better!
(Take me with a grain of salt. I have a long fusion, 14 vertebrae, so I will always have a bit of a strain to put on and tie shoes. But fresh from surgery, this is a good idea for anyone.)
I'm glad you're thinking ahead. It will make your recovery that much easier! Do keep in touch via the board and let us know how you're doing, both before and after your surgery.
One day at a time...
