Great shoes, comfortable, great support for my back and feet. Order 1/2 size larger because they DO run short... I own 3 other pairs of Skechers Shape-ups because they allow me to walk, stand and have a normal everyday experience in spite of my bad back and troubled flat feet. Don't know about this losing weight or toning thing, I am just the same (but haven't been on a diet either). These were my first pair, they have a terrible and potentially dangerous design with the strap, it's not the width nor the type of velcro.. it's that they did not match up the velcro properly, they need extra velcro or a longer strap.. I paid $12.00 for my shoe repair place to put in an extra strip of velcro closer to the opening, have not had any trouble since... Skechers, fix the straps! Please! They are expensive enough without having to invest more to fix, that is why the 4 stars.
