Try buying socks that are made out of moisture-wicking fabric (not cotton). That helped immensely with my blisters. Turns out that your feet sweat a lot--more than you'd expect. If all that moisture stays trapped in your socks, it can cause blisters. I got Nike's Dri-Fit socks, but there are lots of different brand out there.
If you don't have good, well-fitting shoes, consider upgrading your shoes as well.
Why did you get the blisters? I find it really helps to put a big patch of moleskin on the blister area and it prevents it from coming back/ getting worst, and also to use synthetic moisture-wicking socks as opposed to cotton varieties.
I got the blisters from a new pair of sandals. I was taking a walk and of course they started hurting when I was really far from home, so I had to wear them all the way back.
I buy those Band-Aids for blisters, they've got some sort of stuff in them that makes it feel a lot better and not re-form. They're pretty pricey, though, so I save them for occasions where I really need to be able to be on my feet.
Blisters?
