I don't know what Asics did when they reworked this shoe but they ruined it. I have worn this shoe for 10 years.  My favorite running shoe ever.  Now the toe box is so narrow it put my foot to sleep in the first mile.  I was told that you can fix it with going up a size and half (I usually size up one size so they are saying this shoe you size up an extra half).  Not worth the trouble.
