You get what you pay for
Size: 13, Color: Black
First thing I noticed when unboxing was the Strong plastic smell coming out of the shoe
I tried them on and Shoe runs small I bought size 13 and it was way to tight I ended up giving them to a co worker that use size 12 and fit him perfectly, he started walking and the rubber sole was leaving black marks all over the tile floor you could see exactly where he was stepping and left a trail he literally used them for less than 1 hr and ended up throwing them away, definitely you get what you pay for. Reminds me of payless shoes, cheap smelly plastic shoes.

Smell
Size: 10.5 Wide, Color: Black
They feel comfortable. My only complaint is that they smell more like petroleum than a refinery—but what could I do? I needed them urgently.
