Boots = Nepal extremes

In reply to David Coley:

Been using grey wool superfeet with my mantas and trangos. Much much warmer than standard insoles. 

wonder if anyone makes aerogel insoles? That could be about a warm a material as you could get and would make good insoles.

In reply to David Coley:

Sidas do thermal insoles but never tried them myself

In reply to David Coley:

Superfeet Red for me, i use them in my Trango Towers

In reply to David Coley:

I just use some that i found in a pharmacy beneath my normal insoles. Works a treat and only cost £3. My boots were slightly too high volume before, so that was another bonus.

In reply to Dark-Cloud:

I have a pair of Vivobarefoot boots that use the same Outlast material in the insoles as those Superfeet red, they are by far the warmest I’ve ever worn despite the sole being so thin. 

In reply to Dark-Cloud:

I also use these and am perfectly happy with them. I never actually used the original insoles in my boots, just the Reds, so it's hard to be sure of a difference, but certainly I've not been aware of particularly cold toes

In reply to David Coley:I made my own out of some recycled insulated packaging sheet, used it last year in Scarpa Mont Blanc’s and it worked well. It was like this:
