Thanks everyone for the socks and blister product recommendations! I haven't even had a chance to come back here since I wrote my post above (been a busy week!), but very kind of you all, especially RnRGirl for offering to mail me blister products in Mexico...but chances are I would never get them. I don't trust the mail system down here at all. Fortunately, there are lots of stores with good products, so it's not nearly as much of an issue as when we were in Belize and so many items were just not available in the entire country.
There are all kinds of blister products in the stores and pharmacies here...medical stuff is great here and very much on par with the US, so no worries there. Socks, not so much, but I did find some "diabetic" socks since writing my post. They have the toe seams on the outside, and they work GREAT for running. My blisters were minor enough that spending a few days off between runs (I only run 2x a week as it is), was enough for the blisters to heal without even having to buy any special tapes or band-aids. The only thing about the socks I don't like is that they are higher cut than I prefer, making for strange tan lines in sandals, so I'll be buying more low-cut socks when I get back to the US (May 1). The recommendation for wool is a good one, and I love wool socks anyway. Will look for some that are low-cut and not thick b/c of the heat here.
And yes, we are coming back to Mexico after a few months in the US with our families, so this will be an ongoing issue.
Ran 4 miles (plus 1 of walking) on Thursday, so I'm doing pretty well. Not fast but feeling good. Coupled with yoga 3x a week, a couple of bike rides, and lots of walking, it's all good!
Thanks everyone...you are all the best!
