I lift weights in the gym and run inside and outdoors.  For running I always use Adidas.  I needed a lightweight cross-training shoe for lifting and gym cardio.  Reebok's marketing caught my eye and I decided to give it a try figuring I only would be in them a hour a day anyway.  I was immediately satisfied by the look and design.  The first thing I noticed when putting on the shoes was the tongue is paper thin and will try to fold up EVERY time you put on the shoes.  A lot of times you want to be able to throw on athletic wear so that is an annoying feature.  Once on I noticed the shoes were a little snug and the heel lip was pressing against my upper heel.  The first time wearing these shoes I used "no show" socks and it rubbed a blister on the back of one heel.  I've since bought some ankle socks just for these shoes.  Though they are light I don't feel the fit is good enough for me to chance running in them.  I'm a couple weeks in at this point and hope they'll break in a little more.  Overall, I would not recommend this shoe.
