These are really nice kids winter boots. The sole is very bendy and flexible and fairly thin. Although the heel looks built up, it actually seems to be zero drop inside, ie same height heel to toe. Nice and wide and true to size and warm from the fur lining. Edited to add - they also wash well on a shoe wash or delicates wash in the machine!
Comfy, well made and cosy. Very surprised given how inexpensive these were. I haven’t put to test in very wintery or wet conditions but sole seems to have a decent grip. My 8 year old loves the colours and has worn these while scootering
