I have worn Nike Shox since they first came out.  I have read that they are not the best running shoes, but I'm a creature of habit.  I wanted to try something different and these had a great price with great reviews.  I wear a 10 in Nike and I ordered a 10 in these and they fit perfect.

I run on a treadmill.  I had no problem switching from my shox to these.  I ran 8 miles on my first run (my last run on the shox was also 8 miles).  One thing about these shoes on a treadmill, they are a little slippery at first...until you break them in.  If you walk on concrete to roughen them up, this will not be a problem.

These shoes have a wider toe than my shox, which is great because my toes would get sore from my shox (the side of my big toe that is against the shoe is callused from my shox).

I run about 20 miles per week and would recommend these shoes.
