This is by far the most comfortable shoe ever. I bought Sketcher Shape Ups and while comfy they were hard to walk in (to tall for me). The tone ups are perfect and for anyone with knee,ankle or back issues, I have never walked over 10 miles and been totally pain free!!! They are so light weight it is like walking on air.

I am going for my second pair..and by the way they run a tad narrow which is great for me and sizing is dead on!
