Kamik Toddler boys 11 black rain snow slip proof boot drawstring above ankle

Kids size 11 winter boot. Black. In used condition, boot is still great structurally, but the thread has come undone on the fabric at the top of the left boot. Shown in last few pics. Also there is pilling and wear on the insides, can also be seen in pics. Still a great boot! Lots of life left!
