I have a pair of these in size 290 for sale which have been worn around the house but never worn in anger. I bought them to fit in my EU47 Phantom 6000's but they ended up being a touch too small for me. A friend tried them in his EU46 boots and tells me they're a great fit so if you're a size smaller than me they'll work well. These will significantly increase the warmth of your double boots and would be ideal for Denali or similar. I'm using Palau liners in my ski touring boots and think they're amazing.
Price includes insured UK delivery, payment by PayPal Friends & Family. Getting the sizing right on these is a bit of a minefield so if you find they're not right for you I'm happy for you to post them back for a refund.
