"These are my favorite running shoes as they are light and comfortable. I like them better than Free 5.0 which I like better than the old Air Huarache. I run trails and fire roads 8 miles a day 6 times a week.
For future improvement these shoes could use:
1) A little more protection on the front toe as a few there is a small hidden stump or root to stub my toe
2) Occasionally a small pebble, leaf, stick or pine needle will make its way into mm shoe since the opening around my foot does not have elastic like on the Free 5.0 to seal the opening. Also in the summer when it gets dusty lots of dust can enter the shoe.
3) I would also prefer a slip on/off shoe that I do not have to re-tie like with the Free 5.0 or Air Huarache. The elastic enclosure and heel loop would be nice to have and solve item 2 above also.
4) The shoe bottom gets small sticks and gravel stuck in its grooves. Some rocks have managed to punch a small hole into the bottom of one shoe on the heel. So maybe a tougher flexible layer would help. The gravel can sometimes be hard to remove while the shoe is on. So a slip on slip off shoe and can help with this as sometimes the gravel is too uncomfortable to continue running with it stuck in the shoe.
Still with the above mentioned room for improvement, I still buy this shoe.
I was afraid these might not work well in mud and rain and the grooves would be hard to clean like with the gravel but the mud shakes out."
