Quite pleased. These won't be a long distance shoe for me but they are very comfortable for 5 miles and under. Ive seen several reviews where the mesh had busted exposing the toe. These folks must have bought the wrong size. The toe box is snug so I wouldnt recommend for a wide foot. Shouldnt have any problem getting 300-400 miles out of these. I used to wear the Nimbus but they got too stiff for me. The cumulus has returned that comfort.

Update after 1 month of use (50 miles):
Now I am starting to understand some of the complaints. My little toe is starting to hurt after running in these. I could see how the mesh would take some abuse during distance runs.
