Very flimsy. My husband would describe them as a great fit for a baby first learning how to walk because they bend so easily (THE ENTIRE SHOE YOU CAN FOLD IN HALF) and he says it feels like he is wearing slippers and every time he walks over a rock it stabs him in the foot. If he was to walk over a tack he would have a tack in the bottom of his foot. He hates these shoes. He was wearing them to work and within two days they sucked.
