Bests & Worsts Reviews from Amazon

I'm writing this review on the 31st day since the boot arrived in my house. Funny (or not) thing is that TODAY (1 day after the end of the 30 day returning window) the midsole just explode when I was walking on snow, so I had to walk almost a mile with just socks on my left foot. The boot looked pretty good on the first week, but then I saw some blisters on my feet due to the fluffy thing in the sole inside. I just ignored because you know... 40 dollars, but what happened today was unacceptable, the midsole just explode from inside to outside and I simply lost the capacity of use my boots... I'm trying to contact the seller, to get some kind of credit, refund, idk, but it looks like I just lost 40 dollars. This shouldn't happen even on that price point.
