Cold feet in the shoe: Freezer bag over the socks
Pull a freezer bag over the socks, then shoes on and you have warmer feet in the cold .... it works.
Deltoidea: If I want to "stifle" my feet, then this is probably the safest way to do it: o}Also, a high quality athlete's foot can be created with it.
An air and heat exchange must always be present for a good foot climate.
In other words, it is better to wear 2 pairs of BW socks on top of each other so that a thermal pad can be created and held.
I always buy my winter boots half a size bigger, so that I can "stack" my feet together with socks ... but that's what everyone likes the way he likes it most.
In addition, I cream the soles with ABC-ointment, when moving it gets cozy and warm in the shoe ... and the feet can "continue to breathe".
Conclusion: the bag trick is not for me!
