Hey everybody--
I thought I should share my secret to prevent chaffing! The days that I wear a skirt or shorts and don't use it, I am so miserable, so I thought I should prevent others from being miserable too.
So...I use this stuff called "Sport Shield"--you can get it at running stores (maybe even Sport Chalet?). It's a silicone-based roll on that I put on my inner thigh, you don't even have to use that much and a thing of it lasts me about a year (and I live in Los Angeles so I wear a lot of skirts!). In fact, don't apply it liberally because even a little bit works wonders and you can always reapply if you need more later.
I learned about it when I trained for the marathon several years ago. If you go looking for it and someone suggests "Body Glide" as a substitute, don't let them sway you. The Body Glide is to waxy for everyday use and isn't nearly as "gliding" as the Sport Shield.
I just googled it and apparently they have a "blister shield" too but it's a powder--you must try the roll on called Sport Shield! I can't post a link because I only have 17 posts, but if you google it, the website name is blistershield dot com and not sportshield.
Hope this helps at least one person who's looking for relief. I hate sticky, raw inner thighs. :|
