I wear these every day driving a semi truck and walking the concrete floor of a warehouse. We have to have steel toes and Keens are the only boots and shoes I have been able to wear that didn't cut my toes. The Tucson mid so far is one of the best wearing most comfortable boot I've tried. I looked at one of the USA made Keen boots but after reading the reviews and only 63% of people would recommend to a friend, I saw these. I was a bit leary of made in China but so far that fear was unfounded , these boots are very comfortable on the hard concrete and they are flexible enough around the ankle when driving the truck. I would highly recommend these boots to anyone.
