I love the feel and look of these shoes, but the build quality wasn't up to my expectation. The black tread on the bottom began to peel off after the first 3 hours of wear. I wasn't even walking, just sitting in the office and turning myself on my office chair. The black tread part grips the carpet well and it seems the glue isn't very good. I used superglue to fix them, but I wasn't very impressed to say the least.
