I have a couple of pairs of Skechers slip on Go Walk, which tick the box for comfort but they aren't the nicest looking. I have mobility issues so prefer flattish shoes, but I can't wear little pumps as I tend to either step out of them, or spread my feet to keep them on (slapping my feet off ground as I walk). Slip on Skechers are fine, I think cos they cover more of the top of my foot.
This is a long winded way of asking for comfy but more dressy than Skechers recommendations please- that will suit skirts or trousers. Closed or open toe /sandals
Cheers!
