Blue indoor shoes, made of canvas material for good breathability. The heels are also sturdy, and since there's an insole, I think they'll be a little warmer in the winter. When they got tight, I would take out the insole and have them wear them. The inside is wide, so they feel a little big. I think they can be used by both boys and girls. - Color: Blue - Design: Ballet flat style with straps - Material: Canvas - Sole: Rubber sole Thank you for looking.
