These things don't really qualify as shoes. If you were out walking around on the pavement they would deteriorate quickly. If you stepped on something sharp they wouldn't provide much protection and it would surely stab your foot. They're not very warm, but they will make your feet sweat if it is warm. They do qualify as slippers, with the only draw back being you can't slip them on. They're tight enough that they stay on your feet. The size was good for me, size 10.5 US in men's and the extra large fit quite well. I will tell you what I bought them for and what I use them for. I use them for driving. Anyone who likes spirited driving can tell you that pedal feel is essential for accurate braking, acceleration and clutch engagement. These are good for that. You can slip them over your socks as to keep your socks clean and they provide enough protection that repeated pedal work won't result in the sole of your foot getting sore. You can get out of your car with them as long as you don't step on anything sharp and they do provide some warmth, although little more than a pair of socks. With a pair of socks on underneath them it should provide enough insulation to keep your feet warm as long as it's not too cold. You can fold them up and store them about anywhere. I typically just set my shoes on the passenger side floor or on the floor behind the driver seat and slip these on for driving.
They're overpriced though, no question about that. I bought them because I couldn't find anything better.

Title says it all

I like these booties for my yoga class. They stay in place and don't slip on surfaces. My only issue is they tend to hot during practice but otherwise they are great.

I am very pleased that I accidentally discovered these. They don't make my feet feel too hot, and they certainly protect my feet from the occasional splinter that might be on my floor.

To be fair, these booties are not the best idea as everyday slippers. Nor are they especially perfect as beach sandals or locker room flip-flops. There are a lot of things they don't excel at. But when your goal is to travel light (and these days we're not the one who sets that goal, the airlines force it on us) this one pair of booties does a fairly good job at most if not all of the above and more. They've eliminated the need for me to pack the following:

1. Bedroom slippers - because who wants to walk around barefoot or even in socks on most hotel room floors?

2. Pool/spa shoes - well you don't want to wear your dress shoes when you go to the hotel pool, and they frown on you walking barefoot from the elevator and across the lobby plus you get a lot of funny looks if you try doing that in fuzzy bedroom slippers.

3. Beach sandals - barefoot on the beach is fine but getting to the beach is another matter

4. Public locker room sandals "“ yuck, need I say more?

5. In-flight slippers - hey, your feet get cold and you don't want to walk barefoot up to the restroom

The first time I wore them for a hotel ice machine run or trip down to the lobby for a candy bar and a newspaper instead of my Mickey Mouse slippers I knew I was in love with these booties.

Here's the biggest news "¦ they weigh less than a pair of socks (3.1 oz for socks vs 2.2 oz for booties). These travel slippers do it all with style and functionality. Especially when worn around water. Although they are non-woven they do breathe somewhat, not enough to consider them as everyday slipper that's not actually as much of an issue if you slip them on over a pair of casual socks like you might do in a hotel room. Unlike another pair of neoprene booties I bought that were too large these fit my feet literally like a glove and they seem to be stylish wherever I wear them.

The only downside is their ordering page is one of the worst I've seen. There is no size or color chart, instead for some odd reason they use a completely separate page for each ordering choice and almost bury the size/color info in the text, making it incredibly easy to make a mistake. Inexplicably there is an excellent size chart on the tag attached to the booties that you only get to see after you've already bought and received the item. They also assume you want to start an automatic order to buy a new pair every month which gives an undesirable impression about how long the product lasts (only a month?).

I was prepared to give these 4-stars as in "I like it" but after getting used to how comfortable, well-made and versatile they are I would raise it to slightly less than 5-stars taking into consideration their convoluted ordering process.
