Typical Mizuno construction
No hot spots, especially in the heel area that previous versions have bothered me. The heel on the 15's for me fits perfectly, snug without movement. I also find the fit with standard laces much easier to get right without over tightening on the instep. Outside of the foot area seems to have changed from little toe and down.

Got mine on eBay with free shipping at $25.00 off retail prices.
Like the new color selection
So far so good. Some stiffness in the mid sole area with the extended plate but I like it.
Solid construction and revised fit perfect for my feet
None so far
