Here's another pair of Sonic plush slippers.
These types of slippers appear in the USA & England (seemingly over and over, with slight variations) As usual, the slippers feature 3D stuffed plush toy Sonic faces on the toes & blue backs for where the foot goes. These make it look like you're sort of wearing Sonic around, or wearing plush dolls around the house. These are pretty well done, with ears that stand up, well stuffed/sculpted spikes, embroidered eyes & well proportioned faces. Interestingly, they're a bit better put together than some dolls. There's a tag in the back/heel area, which has the Sonic classic logo.
In this case, they're at Primark in the men's section in 2018. They're all-around stuffed & keep your feet warm in sizes 6-8 and 9-12. These are big. Photo & owned by: DarkonDrago
