Bought it for a friend.
He is flat footed and this shoes provides excellent support for his feet without orthitics.
He is touring in China for 4 days now, easily averaging 20 k steps in a day. According to him, he experienced very little fatigue on both if his feet at the end of the tour.
Its not to soft compared to his Rebel 4, that you actually sinks in and not too hard like 680.
