Great arch support, durable, cushy
Bought these for the arch support, which is better than any other slipper I've worn. They are toasty warm. Very durably built - I expect to have this pair for a number of years. I was able to slip in an insole for even more arch support. Sturdy enough for the outdoors, yet cushy like slippers should be. These run short - I had to exchange for a half-size larger, the only time I've ever had to do that, even with other Keen products.
Great indoor slipper!
I tried this shoe on one foot while I tried on several others; it was obvious after trying on several others that my feet like THIS shoe. It runs snugly for its size, but it feels wonderful on my high arches. I use them as indoor (only) slippers as I want the comfortable support of a shoe while feeling warm and cozy in a slipper-like shoe.
TTS length, slightly wider toebox and midfoot
Measured feet 10.9, widest is 3.9 where toes join foot, low /flat arches. Heels i guess are normal to narrow. Low volume feet, flat like pancakes not volume like sausages,lol. I ordered size guide 11, it fit length TTS. It was comfortably wide at forefoot, and moderately narrow at arches, so probably normal width there bc i needed to pull midfoot arch area in tighter. BTW theres no built in arches, so i added my own prescription orthotics after removing thier wool(?) Insoles. Note, the actual bottom under insole had no visible sign of insulation like the inside sides of boots. ISSUE: the laces are difficult to tighten bc holes are small and theres a lot of holes to deal with, so cumbersome = minus 1 star. Next i walked maybe 50 feet on trail temperature 10 degrees or less, my feet were already getting cold. The bottom of shoes isn't very thick so the frozen ground feels like it right under foot. Everyone is different so minus 1/2 star. At 1st try on it felt firm but still close to 'tennis shoes ' level, so thats ok. But for me the heel cushion wasn't as soft as forefoot, after about 300 feet heel was starting to hurt. After 600 feet, i traded out to my softer orthotics. 100 feet later, i was limping. My feet were frozen too. My hands also bc i was gloves off to adjust these boots. I think if i had thicker feet these might have been ok, but with my bony feet i needed more cushion, better sole platform to keep warm. Obviously i couldn't get past that to 'break it n'. Wore medium weight wool socks, darn toughs. Width probably could have fit even thicker socks, and or a liner with thick. These didn't work for me. But hopefully i provided enough info for you to make your own decision. There was no reviews when i took a chance on these. Purchased from REI. Thank goodness for their return policy, so back these go.
Nice, but small
Nice shoes. I felt that they run a bit small. I wear a size 8 in Keen shoes and boots. These felt small. I am returning them to get the next size up.
Wide Toe Box and Great Support
These shoes are extremely comfortable. The wide toe box, sturdy sole, and excellent support make them a pleasure to wear.”
Amazing Fitting Shoes w/great tread!
Total impressed with my new shoes, I’m loving them!
Whyser Slip On shoe
I have been looking for an indoor only slipper/shoe with good arch support. This shoe fits the bill. Very comfortable on wood/tile floors. The sole is thick with great arch support. I’m used to a mule type of slipper but the back of shoe has the ability to fold down at a sewn in crease. So I can wear them either way. Great shoe Keen!
Excellent slippers/camp shoes
These are excellent shoes for house slippers for me. I have very high arches and need slippers/shoes around my house, otherwise my feet start to hurt, especially the hardwood floors. I will say, be careful about sizing. I’m usually a 9.5, but got a 10.5 in these shoes. I’d recommend following the euro sizing for these shoes, not the US size chart.
Not slip-on
NOT a slip-in shoe as advertised. They are beautiful… as well as comfortable once i got them on. But both the top flap and heel portion fold in on themselves when i try to put them on. Even using a shoe horn did not help. Luckily they fit my daughter, who doesn't have as much trouble with them as I - probably because she doesn't have arthritic hands.
