Used in Men's Gobi
I have an old pair of Gobis that needed a replacement insole. I opted for the insulated footbed. They fit into the Gobi without trimming, and do provide a noticeable improvement in insulation when walking or standing on cold surfaces. I have been wearing them for about ten days, and so far cannot fault them. The sizing questions are a little silly: it is pretty subjective for me to say how wide or large they run. I would say they are the same as the Gobi or Ra last.
Insoles Keep Feet Warm
These do the trick in keeping feet warm without losing tactile feel.
I'm using theses in my Vivo's on a Paris trip in December, and they are performing very well. Just the right amount of cushion, and my feet are warm but not hot. You will love them.
