My older son has Keens (Newport H2) in all sizes, but never did the toddler version before now (for our new addition....) Anyways: the velcro closing does not stay shut as good as with bigger sizes where the closing strap loops back and fort.  This size it only goes through the loop once and closes with a little bit of velcro.  My 17 month old unsnaps it just by bending down, it gets a little annoying.

other than that: great quality, and LOVE the red (carnelian) color for a little boy, so sharp and summerly looking!
