I just bought a Wave Fang from Sohubuy and I was able to use them two times already. I'm wondering though why is the logo in the insole of the left shoe already scraped off? Is it just really low quality insole material or what? Here is the picture of the left shoe: Also, why is there no logo in the right shoe, here is its picture: I heard that Sohubuy sells 100% genuine Mizuno shoes but why is this happening? Anyone can help me? Thanks.
