They really do make you sweat. Not been wearing them long enough to discover weight loss but I'm still trying.

These are super hot when you sleep, not cooling at all. They absorb the sweat and oils from your skin. which leaves them looking stained unless you wash them after every use. They do come relatively clean.

Nice shoes. The only problem is if you use them for too long, your feet will be really hot and sweaty.

It make you sweat yes , but its very elastic while you wearing it not really holding your abdomen still look like you have a belly .
I would say it really depend what you do with it and what you need out of it and .

The buttocks have too much bulk too high to be ideal ON ME; our bodies are all different... they kind of make me look fat because of this, but they do realistically make my butt look bigger too, and bigger as in more muscular and shapely.

The drawback is that they REEK!  I don't have a particularly sensitive sense of smell!  I am wearing them under jeans right now and they are making me nauseous because of the horrible smell, which is EXTREMELY STRONG, and comes out through anything you wear over them.  Also, the stench lingers on your fingers if you TOUCH the silicone!  It also stays in any clothes you wear under or over them!

Another thing I should note is that, even though it is cold, they make my butt cheeks sweat underneath the silicone pads, even though the rest of my butt isn't sweating, the rest of my body isn't sweating, and the silicone doesn't touch my butt since I wear underpants and long johns underneath them.

If you want to wear during hot weather, think again! You will be sweaty. But they do look cool.

Makes a loud noise when you run. I tried wearing leggings over but doesn't really help too much. It also has a weird burnt rubber smell out of the package. I washed it a few times hoping it would make a difference but it still smells the same. You do sweat wearing them though... even if just wearing them around the house while cleaning the house.

Was worried that they may make my feet feel sweaty as I live in FLORIDA, but they feel great and breathe well. Most comfortable socks I've ever had. Now only if they came with toes, then that would be even better.

These are magic, I have worn them under clothes in temps from 30 - 72 degrees and have stayed feeling comfortable and not sweaty and sticky while at rest and during physical activity.  I generally wear these while training martial arts which is standing then bursts of physical activity, or while running for 3-4 miles.

I have tried a few different brands such as Nike, underarmour, even cotton ones and every single one of those has a small temp range where they are comfortable with little movement but can't handle moisture wicking once you start either short bursts of activity or sustained activity.

seems are really rough on your skin if your wearing shorts. But it seems to keep you from sweating.

They look very sporty. However the fit is tight so they press too hard on your head. They don't ventilate very well so working out in cool air will cause them to steam up.

Im still really undecided on these.  They work to the point that yes they are hot and you sweat.  But i cant get past how miserable that is.

Before you wash them a few times, they don't deal with sweat very well because they don't absorb anything. Just feel kinda gross. After a few washes they seem to be fine. They're also pretty tight.

Unless you're working they're not very warm. You have to have your blood pumping so they can reflect the heat. Great for a jogger but not a deer stand hunter.

I personally get too hot for them, but that is a personal problem. They do help you to grip the mat so you can do jump thru's better.

When I sweat, my socks and feet typically are soaked which makes my feet uncomfortable. Surprisingly when I took my socks off after cycling 50 miles my feet were not very sweaty. The socks performed the job exceptionally well. I'd venture to say the first pair of socks that really wicked the moisture away.
