Last week I bought a pair of the Skechers Shape-up shoes for work. I have one herniated disc and two bulging discs in my lower back and I am in constant pain. I work where I'm on my feet walking on concrete for my 8-12 hour shifts. With these new shoes my back hurts less than half of what it normally does after a shift. They feel strange walking around, because the sole is so squishy, but you quickly get used to it. If you have similar back or knee problems try a pair out, they will surprise you.
