The item description is misleading.  I kept the size small which was marketed for my grandsons age.  I then ordered what I thought would be a larger size (m), even though it said was appropriate for 11 yr old only to receive another small in a packet labeled M.  I mailed that back and reordered what Im hoping to be a M, even though my grandson is only 7.  I measured his shoe and they are much shorter than the 11 , which is the maximum size of the boots.  Fingers crossed that the 3rd time is the charm!
