A few weeks ago we put out a call for boot testers on behalf of Gore, the makers of GORE-TEX, who is seeking US military personnel to try out cool weather boots made by Altama. They still need candidates for boot testing, particularly with smaller sized feet, sizes 8-9.
This Altama boot integrates two Gore technologies most of you have never encountered until now. GORE-TEX Thermium™ is a new insulation combining Gore’s expertise in polytetrafluoroethylene and silica aerogel, the world’s lightest solid element and best solid thermal protector which was developed by NASA. Thermium is ultra-thin, low-bulk, and non-compressible resulting in a lower profile boot than you’d expect for cold weather. The insulation is thermally mapped to target only areas where needed: around the toes, since they become cold first.
In addition, these boots also feature GORE-TEX Extended Comfort technology. Like all GORE-TEX, these boots will keep your feet dry from external water, but they are engineered with the next generation of footwear laminate technology for warm conditions which has a breathability ~2x higher than the existing technology. More breathability means more sweat can evaporate through the laminate, and more evaporation means more heat loss and less clamminess.

Could try opening up testing to civilians/NG personnel.
Just received mine today!
