Dian - any thoughts on why it would only happen on top of the legs instead of all the way around? Just because the sun is hitting the tops of my legs? Granted, it's 90+ degrees when it strikes. Not sure what the grippers are - shorts are Cannondale, grippers are smooth/clear. I've never been allergic to anything before. You're thinking hives as opposed to rash? It seems like many of us get this sort of thing... way more than I expected when I posted.
Thanks.
