Men’s FluidFlex™ F.K.T.™ II Shoe is rated out of 5 by 3.
Rated 5 out of 5 by Watts from Great Shoes Just did a nice 21 mile hike/trail run in these awesome shoes (after a few short break in runs). I was in the Enchantments wilderness in WA. Great performance on loose mountain kitty litter, awesome traction on early June snow pack, and great stick on the cascade granite. No blisters, not even a hot spot (when paired with good trail running socks). The shoes unsurprisingly got wet in the snow, but I was amazed at how quickly they seemed to dry out. Good flex in the shoe, without killing my arch.

Rated 5 out of 5 by Tom99 from Another winner! Comfort is important to me. It all starts from the ground up and the FKT’s are a great place to start. They are well manufactured with no uncomfortable seams on the inside. The cushioning is perfect and makes it easy to wear them for a good part of my day. The lacing is well designed and allows me to tighten them so they feel like a part of my feet. The arch support is not too high so they allow my feet to pronate naturally and keep my feet from hurting. This is another example of why I wear Columbia shoes and boots. The designers have the end user in mind. They also look great!

Rated 5 out of 5 by HikingCouple2 from Very Comfortable I was very hesitant to buy these shoes for my boyfriend because there was no reviews yet but I trusted the process where Columbia helps you find what kind of shoes are best fitting for your run type and so this shoe and another shoe were the 2 that was given for choices and of course I choose this one and my boyfriend absolutely loves them. He said after the second run his feet was comfortable, didn't give him blisters or wasnt forming at least. He said he was super impress because usually he likes to try running shoes on first of course but Columbia really guided me on what to get from the web and now he loves them. At first when I saw them, I was like oh no they look to narrow because it really does and very long perhaps because of the narrowness look but NO they fitted his wide foot. Great vibrant looking colors and also the shoe laces stay on very well. Thanks Columbia again!
