I like these shoes so much, this is my second pair  (exactly the same shoe).  I have had good luck with Ryka shoes in the past.  They fit my foot properly & feel really good.  Shoes are a very personal item & running shoes especially.  What works for one person, may not work for another.

I am petite (5'3") and @ 112 Lbs.  I run approximately 2.5 miles, 3 times a week & on the other days, I walk fast.  I wear these shoes for both forms of exercise.  I wore these through a Midwest winter.  My route is on a paved road.  I tend to be a foot pounder - I put my foot down hard.  My soles always wear out while the tops of my shoes look almost new. These shoes have held up well.  I wore the first pair for 9 months.  I really should have replaced them a couple months ago but I don't like shopping for running shoes.  Most podiatrists recommend you replace your running shoes on average every 350-550 miles for good support & fewer injuries.  If you are overweight, you should err on the lower side of this mileage.

I like the mesh fabric on these shoes because it lets a breeze blow through.  It helps my feet stay cooler.  The insole is removable & washable; just throw them in the washing machine & air dry.

The fit is true to size.  I wear a 7.5(M) & these fit perfectly w/athletic socks.
