I love love love these running shoes!  I have been using the progrid guide for over 5 years (multiple pairs) and these give me just the right amount of support. Roomy in the toe and snug in the heel - just how I like them.  These shoes last a long time - I use them only on a treadmill, typically 15-18 miles a week.  I have arthritic changes in my knees and these do a great job of keeping the soreness and impact to  minimum.  Lightweight too!
