did you try the grounding? YEa dont worry if its cold. I mean try and take it easy and dont overdue it but I few minutes with barefeet wont hurt you. Luckily I am here in Texas and we have been having very short winters lately and so it often feels like spring here. I am able to get out and about without any problems related to the winter.
you can also go ahead and try the grounding bands which are cheap. Hope the grounding helps you!
