These super soft seamless socks are perfect for kids with low profile bracing such as SMO's or UCBL's. SmartKnit SMO Interface Socks help reduce pressure and increase compliance. Core-Spun yarns with Lycra and form-fitting design result in children's socks that 'hug' the foot like a second skin -- they don't wrinkle or bunch. The non-binding Halo top fits comfortably without slipping down the leg. Moisture wicking properties help move moisture away from the skin and provide a comfortable coolness. Their heel-less design allows a fit at various heights - adjust your size selection according to how far up the leg you want or need the sock to go.
