I had to get a strap version after 2 years of wearing my slip ons and 1 year with my clogs....both with NO SIGNS OF WEAR!!
The soles leathered up nicely and have good arch support. Excellent customer service by UNITEDSHOES ~5 day FREE delivery from Germany to the East Coast of the US (Incredible)!! These were authentic and in perfect condition at a great price. Very happy!!!
