There is a pronounced lump in the shoes right arch support.  It makes them unwearable.  I'm sending them back as I write this review. Update 7-25-15  I have now had 3 pairs of these shoes, all have the pronounced hump in the right shoes arch.  It is very uncomfortable, and I would warn all of you to stay away.  Although this shoe is rated very high, Asics has a major problem with this shoe!
