Sometimes I work as a caterer in a relatively casual setting, and we dress in our own clothes. The idea is "look like a guest, but with food." As a big fan of Keens, I bought these sandals thinking they would be dressy enough to wear with a casual-yet-nice dress, yet still give me the support and cushioning I need to be on my feet. Not so much.
First of all, I immediately noticed how kinda flimsy and cheap they seemed. The straps were just glued in, with visible gobs of glue. The heel strap is adjustable, with a faux velcro closure: It's not a hook-and-fuzzy duo as per regular velcro, it's more like both sides are hook-y, plastic-y stuff. I don't see them lasting long, and my skinny feet needed them a bit tighter than the strap would allow. The buckle worked fine for me, but the real killer was the spot where the toe strap joins with the heel strap, on the inside. That chafed at my instep right away. I wore them inside, on carpeting and bare wood floors, for about an hour. I decided these are not the shoes for me, and returned them.
I live on a pretty remote island off the coast of Maine. I spend my winter days on a lobster boat. It gets face-splitting cold, and then I come home to an uninsulated house. I bought these Nuptse Booties to wear around the house, as slippers. I needed something warm, and I also wanted a sole that would take me outside on a dash to the woodpile or the chest freezer. Additionally, there had to be a tread that would keep me from slipping down the stairs. I thought these would be a great choice based on the down and the sole.
The good: As slippers, these are ok. They are warm most of the time. I feel comfortable wearing them on the slick hardwood stairs. They seem fine to run out onto the porch in, though I have not yet experienced their "amazo-morph" grip technology, or whatever. Admittedly, they are not quite cozy-curl-up-on-the-couch-with-them-on like some slippers, but they are serving the purpose. They were true to size. And they're kinda cute. I like cute.
The bad: I got these on sale, but they seem to go for about 80 clams. For that, I feel I deserve more support around the ankle (these feel saggy, despite the elastic inside). Furthermore, they are not very comfy. I have noticed my feel feel tired after walking around in them on the hardwood floors. They should be more cushy, with some down or foam on the bottom. I stuck some insoles in there, but I feel like I should not have to based on the brand name and price. And sometimes, yeah, my freakin' feet are cold. I mean, come on! I'm INSIDE! Under a BLANKET! But OK, I admit it's nippy in the living room.
The ugly: Some people seem to wear these outside, as boots. That seems laughable to me. There is no support, they are not waterproof, and down does not insulate when wet. I would definitely NOT recommend purchasing these with the intention of using them as anything other than slippers or tent booties.
Backcountry as a vendor was great: best price for these ridiculously spendy slippers, and free, fast shipping. I look forward to shopping here again.
