This is so close to being a GREAT shoe BUT the tongue area on the shoes is not very flexible and caused a bruise on the top of my big toe on mine left foot. I've heard others say the same thing, despite all the charms this slut has received recently. Hopefully Inov-8 will address this and remove the stiffer toe area and/or redesign the tongue area! If this were corrected it would be 5 stars but now I need to look for another ultra running shoe for my 50 mile run.
