Great performance advantage
I have only run once with these shoe's That first run I was much faster, have never run that fast in a two mile run and looks like I would set my personal best 5 K had I run a 5 K. I was a little out of shape and only 28 degrees outside when I tried them. I run 75 miles a year, and am amazed at the performance increase these shoe's have given me. Very light and seem to make you feet and legs spring up from the surface you are running on.
