Vivo Barefoot Tundra ESC Review

I will put an insulating insole in them before next week.

Which one are you looking at?

These came up in another thread about winter insoles.

FWIW…

I’ve used nice insoles inside wool liners and have found in many pack boots they really don’t improve warmth - I believe it negates the warm heat trapping of the wool bottom below it.

Good traditional pack boots have often imbedded insulation in the sole itself often referred to as a frost plug. Basically a dense foam layer above the traction sole then a hard inner sole over it. The foam is non porous type. Then the inner wool bootie sits atop.

Thicker wool inner sole helps some but the heat is robbed from the ground up. Hence my thought was to replicate a frost plug from under the wool liner atop the flexible traction using the semi rigid non porous foam foot bed and liner atop that. This also maintains the flexible barefoot foundation of this boot.

In my tests it helped significantly. Noticeabley better than a 9 mm wool inner sole replacement. But as a fellow student, Form encourages testing yourself and you could try those and compare.

I stand firmly that this is a great boot and the only trade off is ground cold which I’ve solved for, for me. It’s still a superior option to a warmer pack boot that trap moisture.
