I have Keen casual shoes which enticed me to buy the Snowport boots which I love. That caused me to buy the matching Newport Sandals for summer and now the Targhee II hikers to replace all my sneakers. I have loved every Keen product I have tried but the jury is still out on these until I wear them more. The insole is not as comfortable out of the box as all the other Keens that I own but I am hopeful that they will get better after breaking in more. After all day wear the ball of my foot was hot and sore so I tried another insole but quickly switched back to the factory insole because the high priced insoles were worse. Keen makes their shoes wide and I have wide feet so they are great for me but this model is a little loose in the heel unless I pull them tight which is no big deal but not the glove like fit of the other Keens. People with narrow feet will probably not fit well in Keens. I probably have a measured size 12E but wides are hard to find in most brands and big sizes. I have worn size 13 for many years just to get a wider sole and more toe room- just can't wear pointy toe shoes. Many brands tend to run short anyway or lose much of the toe room for "design" purposes. All my Merrels in size 13 make my toes hit the front end of the shoe when walking down hill and have little toe room but not Keens in the same size. Unless you are comfortable in Merrels I would probably suggest a half size bigger for normal feet. I love the big toe box which gives plenty of room to wiggle the toes and doesn't jam your toes going downhill. The blue/slate laces and trim with Brindle leather really look great with jeans and the soles are much better than sneakers in most terrain. I almost bought the Newport Hikers instead since they match my sandals and boots but I thought these looked better and had more coverage for late winter/ early spring. I may end up buying the Newports anyway just to compare.
