These are super cute slippers! Perfect for your Thomas the Train enthusiast! These slippers have rubber bottoms and cotton sock uppers. It says: “Built for Speed!” On the top of each slipper. It will give your little one a good grip of the floor as they move around. I’m rating these in GUC because some of the threading on Thomas’s face is fuzzy (see pictures & video). The size tag on this slipper says 8, but it fits more like a 7, which is why I listed it as a 7. I included the measurement in the photos. All my closet items come from my smoke-free, pet-friendly household, and are laundered in scent-free products. These slippers were never put in the dryer.
