UPDATE: It's now been two years since I purchased these shoes.  I use them three times per week for intense treadmill power walking.  They continue to be outstanding in durability, comfort and "breathability".  I am extremely happy with them and plan to order another pair just to have on hand for whenever my current pair wear out.......which at the rate they're going will be several years from now.  There is no other shoe that I would ever consider for exercising now that I've been spoiled with these shoes.  Well-worth the money is an understatement!

I spent quite a bit of time looking for a new pair of exercise shoes.  I've worn top-of-the-line Asics in the past but they recently have been causing the toe pads of my feet to really burn.  Hence, I needed a new pair of good quality exercise shoes that wouldn't cause the burning toe pads.  These shoes were exactly what I needed and wanted!  They are light weight, have holes in the bottom of the soles for air circulation and the burning toe pads have completely stopped.  I couldn't be more pleased with these shoes.  A word of caution, though:  Don't wear these shoes outside because of the air circulation holes in the soles.  They can cause moisture and dirt inside the shoe.  I strictly wear these exercise shoes on my treadmill only.  I have a pair of flip flops that I use for coming and going to my treadmill room.

I'm positive if you're looking for a great pair of light weight exercise shoes that really allow your feet to breathe while exercising, then these are the shoes for you.  Good price, great quality!
