I just broke my last Nike Air Zoom Mariah out of the box. (I wonder what I could have got for that on Ebay.) That has been my regular training shoe for about the last eight years. I tried the Zoom Streak XC. They're not too bad but they lack the forefoot cushioning and don't seem to have the smooth ride. I think the thing that makes the Zoom Mariah so good is that the zoom unit is full length. Even if you can find a shoe with forefoot zoom from Nike, it is a separate unit from the heel unit. Any suggestions on what is the closest thing to the Zoom Mariah that is out there, Nike or otherwise? Thanks.
