If you are interested I have a pair of Western Mountaineering Flash Booties, cranberry in sz. large. I have never used them. I bought them last March specifically for a spring skiing backcountry trip. We ended up skiing into a yurt instead of camping out, so I never even put them on my feet.
I'll shoot them to you for $40 and I'll pay shipping. Let me know if you have any questions or need pics.
