I wear Salomon Ivy boots but with the speed lace which gives a little more control than I felt I had with the Boas. I hate the Boa system though to be honest. As for relief from pain and numbness there is this tape call KT Tape and it using kinsieology (sp) to apply pressure and relieve the tension in the muscles. As a temporary remedy I would suggest buying a roll. It's around twenty bucks and you can get a few uses out of it and wear it for days at a time, it can get wet, bends with your skin and doesn't pinch or hurt. Kinesiology Tape | KT Tape
Check it out here. I use it for my knees. But in the end, you need new boots or liners eventually. If you can try on guys boots too and see how they fit too.
Good luck and I hope you get more time on the mountain.
