I bought new liners to replace ones in my 10 year old Sorel Blizzard boots. While I took a chance on whether the size would be right, the liners are everything I thought they would be. Incredibly warm and dry, I am ready to be in the snow all day now.
replaced a -40 rated boot liner (Baffin) with these. good fit, keep my feet nicly warm down to around 10 degrees in a rubber boot (not a Pac boot). was hoping they would fit in my 2000 gram TU boots (ordered the boots 1.5 sizes larger than usual) but still too tigh a fit. fortunately the boots fit just right using the thick 300 weight polartec socks (which I also ordered at the same time).
