I ordered two different types of Trimfit socks for my daughter. I ordered both sets the same size (shoe size 9 to 2-1/2 / sock size 7 to 8-1/2, aka small). The white No-Show Sport Liner socks ran very small compared to other socks. I don't think they will fit so I will be sending them back and ordering Wednesday. I wasn't sure if they would have a plush lining inside, but the fabric is the same throughout.
