Wore these this morning for a 3 mile run and they worked out great!! This is the first run of the year for me, I took 2 weeks off:) and the first time I wore these shoes. Very light weight, I normally wear a 8.5m and went up a half size to 9m, they fit perfectly! I got the aqua colored ones, very pretty and comes with an extra set of shoelaces (Bonus!) and a fabric bag to store them in. My legs felt great, no pain in my feet either; the shoes did not rub and cause bilsters. I could have run further but had to get ready for work. I will buy another pair of these.
