I have always purchased the Brooks Addiction Walkers but felt I needed a cooler, breathable shoe for the summer.
After calling the company and verifying that this is the same base as the walker, I ordered these.
They are extremely comfortable.  The only thing I would say is to be sure about the size.  I wear a 9 in most shoes but after being fitted for the Brooks at a local shoe store, I got a 9.5.  For some reason this mesh top feels a bit shorter than the usual 9.5.  Perhaps it's just the soft top that is giving me that feeling...or maybe they do run just the smallest bit shorter.
