Regarding Trent: Trent's foot is a little wider near the toe than Matt's foot. Some shoes will fit Trent, but you need to wiggle the toes in to stretch out the front of the shoe when you put it on. I recommend doing this on a foot without a sock, as the wiggling and stress on the sock as you force the toes in may damage the toe of sock. Once the shoe is stretched, it will be easier to put it on a second time with a thin sock.
Shoes will fit over thin socks. Please see the BJD Shoe page for more styles that will fit male dolls, including sneakers.
