I've been wearing the Mizuno Inspire since the Inspire 5 (2011) and it's still my most comfortable shoe. Unfortunately, the durability of later versions of the shoe was questionable due to internal wear on the back of the heel. I hope Mizuno fixed this issue with the Inspire 16, but only time will tell. Another issue, which is actually more of a minor inconvenience, is the flat laces. Although they stay knotted on long runs, for some reason I find the flat laces particularly difficult to untie and plan on replacing them with an old pair of laces. Otherwise, these shoes are great, especially when you can get them at a reduced price.
