The original Sky Wave jersey (size 12) fits better than the Sky Wave 4 and is also a bit overpriced. I rode Wave 25, it's much better than Skywave 4.

Size: 11 Fit: I'm 11 in Mizuno and 11.5 in pretty much every other running shoe. As with most Mizunos, they're wide for medium width, but precise in length. a size smaller. On the other hand, if your foot length is a more important factor in sizing OR you like some room in your shoes, just order your typical size. Cushioning: Without a doubt, this shoe is made for mile-eaters. about it. Depreciation is unearthly. If you enjoy running long distances, this shoe should suit you. Traction: Traction

I didn't buy it for running but for everyday life and cycling. Great cushion and support for aching knees and backs that feel better after wearing them. I wore size 12 for all other shoes so I ordered 12 and 12.5. I left 12.5 which fit perfectly.

Insanely comfortable. The internal design of the boot provides a snug fit to prevent slippage on long runs. Slightly tighter at the indent, ideal for heavier runners.

Perfect fit and very comfortable for my heavy body and wide foot. I've used them for walking 2-3 miles at a time and for light running so can't speak of serious running.

The new model #4 took everything the #3 lacked and this time Mizuno has created a near perfect shoe. Yes, it's at the top of the price range, but you get what you pay for. Damn good!
