Inside seam liner came off on left boot. Did not affect the performance. Wore these in Alaska for three days of fly-in ptarmigan hunting. The front rubber held up well against the willows and the boots kept my feet dry while crossing small streams all day long. After a few months the inside material is falling apart on both boots. I can not return them so I will cut out the inside lining as it continues to delaminate. I would not recommend these boots.
