I purchased these hoping to give me another option to my glizzy max’s, and while the rocker in these is pretty smooth it doesn’t quite work with my gait. These are pretty comfy yet responsive, but not quite as cushy as the glizzy’s imo. The upper is thinner and more breathable than I expected it to be based upon the pictures. With this being said, I personally think these fit more like 11’s than 11.5’s, but I have somewhat wider, fuller feet. I only took these on one run for 7 miles. Will not ship in original box. Venmo or PayPal preferred.
