[Highland Park] Looking for boys' snow boots, size 3-4

Hi everyone. My 9-year-old son's snow boots have been ruined, and I've been unsuccessfully looking for a replacement pair for days now. Meanwhile, he can't go out and play in all of this awesome snow because he doesn't have any appropriate footwear! So - does anyone have an outgrown pair of kids' snow boots in size 3, 3.5, or 4 (bigger kids, not toddlers) that they'd be willing to sell or give away? If you have anything that would fit the bill, please email me as soon as possible and be a 9-year-old's (temporary, at least) hero. :) Thanks! Julie Wellesley Ave
