Customer Reviews Outdoor Research Tundra Slip-On Aerogel Booties

Wear them every day around the house. Not the commies house shoes but thats not what they were designed to be. Really warm but breathable. And lightweight.

These slippers are warmer than any I've worn before, especially given their minimal weight. My feet sweat in them when I wear them inside the house for any amount of time, so for me it's best to use them in truly chilly weather or just intermittently inside.

Awesome slippers for a cold place. However one slipper all of a sudden a lump appeared out of nowhere on the right side of the right slipper. Not sure what it is but its almost like there was a arch support in the slipper that was on the edge of the insole.

I have waited and watched for almost a year to get the XS size of these booties, which for women is stated to match shoe size 5-6. Every single pair of shoes I have had for 20 years is 6, and these booties are just not close to that size. My whole thumb width fits between my toe and the inside tip of the slipper. I've waited so long, and there is no smaller or kids' size option, so I am keeping them even though they are too big. The heel flap keeps them from being too floppy, and they are warm and comfortable. I just wish they were close to true to size.
