Reward your feet after a day of roughing it.

There is nothing better than slipping out of your hiking, mountaineering, or ski boots and into a pair of the lightweight Western Mountaineering Men's Flash Booties at the end of the day. These babies are packed with warm goose down insulation to help thaw out cold feet and give them some good ol' TLC. The Flash Bootie is primarily intended for use indoors, in your tent, or even in your sleeping bag, but a reinforced sole does allow for quick trips outdoors.

Light and Warm

  • Familiarity: I've used it several times

I wear an 8.5 and I bought the Med. I think they fit the way they are supposed to. They are light, fluffy and warm. I bought these for mostly cold weather camping. You can venture outside but do it quickly and carefully. If you're looking for something that is more rugged, try the expedition or bootie models by Western Mountaineering. Honestly, beside the oven effect, you barely know they are on.

I wear a Mens 8 1/2, occasionally size 9....

I wear a Mens 8 1/2, occasionally size 9. Would the "Medium" be tight? Would the "Large" be too loose?

Responded on

I wear a size 9.5-10 and just got the large and they are huge. I have more than an inch and a half to move around in. I'm going to swap them for mediums. I'm not sure if I would go with a medium or small if I were you but I'd say that medium you'd definitely have room.
-- edit--
I'm noticing a discrepency between the EU sizing and US sizing on their sizing chart and I feel like the EU sizing is definitely more accurate to what I got so I would recommend going with that.

Feather Light

  • Familiarity: I gave it as a gift but have feedback to share
  • Fit: True to size

I got these for my GF for casual use because she likes my somewhat beefier WM down booties. The red color is very feminine and she loves them.
However, on a functional note: these are so ridiculously lightweight that I would recommend them for any backcountry enthusiast with cold feet. The warmth-to-weight ratio is as good as it gets. I would make sure not to walk around much at all in these, though, as they are the most delicate bootie WM makes.

Will you be getting in more sizes any time...

Will you be getting in more sizes any time soon?

Hey Greg,
You're in luck! We more of all sizes in throughout the next month or so, just keep checking back!

Well Made but slippery bottom

  • Gender: Male
  • Familiarity: I gave it as a gift but have feedback to share

Bought this product for my wife. Very well made and very light. Had to send it back because the bottom was too slippery for her. She almost fell twice after wearing them for about an hour.

Got to use these for the first time last night cold camping in northern Minnesota. I put them on inside my tent and instant comfort! I love them. So warm I had to take them off in the middle of the night because my feet were too warm. I only plan to use them inside my sleeping bag. It was 0° F and I was happy.

Good for in the Sleeping Bag

First of all, I got these to take with me winter alpine climbing. My feet tend to get quite cold in my sleeping bag within my bivy bag within a snow trench laying on the snow. I got these guys because they're smaller than the others and I assumed they'd compress very well. And they do! They are also very warm. They have definitely achieved my purpose in getting them. I had no intentions (and still don't) on using them to walk around camp in the snow. They wouldn't work well for that (but that's what the others are for). Walking around camp I tend to wear my boots loosened up. So if this is what you're looking for, these guys will give you a super lightweight option that will serve you well.
