Poor material longevity.
"Very good width vs length. Comfortable. Beware these (mfg Vietnam) are not robust ultimate all terrain beasts. Teva does NOT stand behind their product, you will get NOTHING not even the broken footwear back! After 3 months: the sole de-laminates, blocks fall off, shank breaks loose & then core of footbed cracks apart under front strap. The straps are the only robust part!"
