Because I was happy when I discovered the Spring Step "Naples" style clogs, I decided to try this style, "Firefly," which looked similar enough to the Naples style in photos. The Naples style clogs are just barely adequate but not roomy in length ( it is true the Spring Step shoes seem to run short, compared to other brands, as noted by others). Because the Naples style clogs are so comfy generally, with a nice, wide toe box that allow your toes wiggle room while not feeling too wide at the heel, I went ahead and ordered the Firefly shoes; to my disappointment, my toes hit the front of the shoes on the Firefly style, even though both styles were the same size, and so I returned the Firefly style ASAP, at no charge, because I dropped them off at a UPS store. By the way, FYI: Neither of the two Spring Step styles I mention has a removable inner sole, although I felt there is adequate arch support and the inner sole is comfortable. A removable inner sole is a nice thing to have in the event that an insert is needed. I would have rated the Firefly shoes higher if they weren't so short; perhaps getting one size up would have solved the problem.
