Hush Puppies kids unisex shoe 3.5w

Slip-on Hush Puppies shoes, size 3.5 wide. Distressed blue gray/green with a light colored rubber sole. My son wore these about 5 times. The soles look dirty because they are not white to begin with, but I did feel that the shoe started to look worn very quickly, as you can see from the photos of the sole and overall quality of the shoe. We lost one insole and then he refused to wear them, see last 2 photos. Very comfy tho and sold out. This item is eligible for my buy 4 for $20 offer.
