I've been running in Mizuno Wave Prophecy shoes for 4 years. I had (2) pairs of WP3, (2) pairs of WP4, and (1) pair of Lamborghini White Special Edition, (my favorite shoe of all time); but I had a disappointing experience with the new model, WP8. I played it safe and ordered 1/2 size bigger for some wiggle room. Upon putting on my WP8s I felt extreme pressure and discomfort in my lower heel from the plastic outer shell. Also the front part of my foot felt way to tight. My foot size is medium in width. I never look for wide shoes. WP8 were designed too narrow. I love Wave Prophecy series, but I am disappointed I cannot wear their newest model for long distance running.
My review is not a reflection of HolabirdSports, they didn't design the shoe. The customer service I received was excellent and professional. I was able to return my shoes for a refund.
