Tuesday ordered late and already arrived Thursday. After I unpacked the Hot Sox (been Are in a huge cardboard in it, where would loose reingepasst 12 pair Hot Sox) and the manual have read, I have warmed it in the microwave for 75 seconds.. Then I got a heat test done with your hands and you came to meet me a few grains. In one of the Hot Sox is inside at the front the sewn seam was about 1cm long open where the grains have escaped. Habs now sewn by hand and see if I'm going to have fun off still.
