The style update "V4" of this shoe has much less padding around the heel notch (top of the rear heel) than the prior versions. It's a shame because I loved prior versions of this shoe (this is my fourth pair of MX608) but the new V4 design gave me blisters at the top of my heel the first time I wore it for a long walk because the rear edge of the shoe is so sharp.
