text: Construction and cushioning as per the normal high Kayano standard but as reviewers have mentioned, the toe box and overall fit is tighter than previous versions. I was undecided for a while as to whether to return for half a size up but decided to keep them as the cost of posting them back from New Zealand and back again was too expensive around $60 US. Hopefully blisters and black toe nails do not follow. Very disappointed that Asics have changed the fitting of the shoe.
