Good but not for me.

I have quite a few pair (4) of the fusion run I use for various activities and love the fit and the rocker which is 1/4 length. The Mestari 1.5 however uses a longer fulcrum and the control is just too much for me. The cushioning is actually quite good for a 25mm forefoot but it's just too stiff, especially around the heel and midfoot. I still give it a good rating because is well made, but I just can't wear it.

So Far, So Good

I don’t have many miles on this pair, yet, but I’m optimistic about this shoe’s potential. The wide is wide enough to accommodate my orthotics. Would buy again.
