I prefer sneakers 100%. I have slip on ones I don't have to tie and are easy to put on because I couldn't really bend over much after my surgery. Also have slip ons for around the house that are suuuuper comfy. I have accidentally walked out in them before because they're just that cozy. But they also fall off easier since there's nothing in the back. xD
My nurse at the time told me to always keep shoes on in the house so I don't step on anything just in case, especially since it's hard to look down these days.
