Birkenstock Sapatos de segurança QS700 Microfibra COM biqueira de aço

I bought this shoe a month and a half ago for my construction job. I’ve never had such buyers remorse. When I first started wearing them, they chafed the back of my heel something awful. I tried my best to weather through the pain and thankfully after a couple of weeks they loosened up to where I could wear them comfortably. Then they started to tear at the seems. Awful buy! Do not purchase!
