Last night I saw a post asking about rockered soles and I can't seem to find it this morning, even after a good nights sleep. My question....I successfuly wear Xelero shoes for walking but would like to find a boot with a similar sole. Specs....I am 67yr old female going tonorthern Spain to do some hiking. I have a fused left ankle and a replaced knee on the same leg. Could any of you, what appear to be much younger folks, help me locate something. I live in the mountains of Western NC and there are no stores handy.
