I cannot wear them for a whole day. One possible reason is that I live in the swamps of Louisiana and the heat and humidity is really oppressive. Seeing as these boots do not breathe at all my discomfort may be attributed to that. I will be able to test this theory when the seasons change and the weather becomes cooler. If they continue to hurt even when it is cold outside then I will know for sure that these boots and my poor feet are not a match. UPDATE: Its now Oct 10th 2015, Yup these boots suck my feet are soaked in sweat and hurt so much after only few hours and its not hot anymore. I haven't had sweaty feet problems ever before. I like the way these boots look and i wish i could wear them. :-(
