Thanks for the tip! I'll try walking backwards tomorrow! It's probably the last day I'll be able to use the pool for the rest of the week (back to the treadmill for a few days ). We have an above ground back yard pool, but the weather this year has been awful! Tomorrow's forcast is sunny and 83 degrees -- great weather. But then the cold front moves in along with the rain -- rest of the week and into Saturday is 60's for highs and rain!

I started wearing water shoes and it's helped -- the blister is gone and I'll continue to wear them -- I think the blister was from slipping on the vinyl liner.

It must be great to have an indoor pool to walk/run in so you aren't limited by the weather!
