Hi Terry...I started using a 4 wheel rollator walker at about 8 months post-op. There are times when I'm pushing it where it feels like it will get away from me, so at times, I find myself pushing down harder on it as I walk to slow it down. I really find that crutches are the most natural feeling for me and I use them whenever I go out. I have both underarm crutches and forearm crutches I use. You do need to even out your legs for optimum mobility. My husband has made all my shoes by glueing soles from one shoe onto another to get the right height. I can send you picture if you'd like of my shoes. There is also something called "even Up" you can buy off Amazon for about $35 to strap to your current shoes to add height. I've used it on my tennis shoes. Good luck and wishing you wellness......CIndy
