I bought a pair of the Eleven81 Winter Booties just about a month ago. I put them on for only the second time yesterday and the zipper broke in half. So it is easy to see that I am not happy with the product but I am hoping it was simply a defective product.
I have contacted the company so I will report back on the customer service hopefully soon.
By the way, the booties were warm and comfortable and seemed to fit good, the one time I was able to use them.
