Racer Running Sneaker

[This review was collected as part of a promotion.] They were comfortable enough , but the inner sole disinegrating after 5-6 weeks of wear ( 5 days / week , while working ) Is beyond ridiculous. It appears the comosition of the soles is made up of a good amount of paper-like material , it crumbled when I tried to remove the rest of the sole. They are now unwearable as It's been beyond difficult to remove the remaing section & if I were to try to just overlay new inner soles on top , I'd always feel it.
