KEEN Men's Uneek SNK Chukka Waterproof Boot

Definitely size up at least a half size. I usually wear a men's 9 in KEEN shoes but in UNEEK SNKs I wear a 9.5. I ordered the 9.5 in this and it was a little tight with thin athletic socks and my toes hit the top once I put on some medium-weight wool socks in addition to being too tight for comfort. I returned for a 10, and while it's a little looser on one foot than the other (darn these odd-sized feet!), they are so comfortable, easy to slip on and off, and need zero break-in. Stoked to put these to the test with our rainy PNW winter!

If the pull loops on the upper back of the shoe were big enough to put a finger through and actually pull the UNEEK on, this shoe would be a 5. I used to have a similar shoe from Timberland that I loved for the winter weather. These could be just as great except for that one issue. Other than that, I love them
