I remember buying the Skechers Goruns when Meb first signed. Here's my take:
The midfoot bump puts you easily on your midfoot/forefoot. They are uncomfortable to walk in, but they feel great when running...are these the first popular "tuned" running shoes?
The lack of a removable insert makes them stick to the bottom of your feet, which feels great at speed. I don't know why this isn't universal in racing flats...although these shoes are only trainers.
The new hyper material makes these formerly minimally cushioned shoes seemingly much more cushioned.
So far, they are holding up well. Arguably, the top mesh is a little too flimsy, but the fit is great.
Far better than the last gorun I bought, a year or two ago.
