Although home cleaned, there may be some remaining dirt such as sand. My child outgrew these in 1-2 months, so there is some wear and tear, but the soles of the shoes are hardly worn. The Velcro straps fasten securely. I think these shoes can still be worn a lot, so I hope to pass them on to someone who needs them. Please refrain from purchasing if you are overly concerned about minor details. Shipping will be in simple packaging with only waterproof measures. Size: 20cm~
