Target is introducing a new line of sneakers with a clever design that allows them to grow alongside the wearer, extending how long they can be worn before they’re too small. The ÜNOS by Sz shoes (which is short for (“U Need One Size”) are available in kids sizes for $34.99, and adult sizes for $49.99, in sixteen different color options.

The ÜNOS by Sz feature a sole that’s split into two sections by a Z-shaped channel, but each side remains connected by flexible fabrics. The design allows the shoes to expand in width and length while still being providing a secure fit — up to a half-size in the kids version, and up to a full size in the adult one.

The shoes were created to solve several different problems with footwear. The most obvious is that kids often grow out of their shoes long before they’re worn out, and sometimes end up having to wear uncomfortable footwear when parents don’t realize they’re too small. The ÜNOS by Sz will extend their wearability as a foot outgrows the shoe’s original sizing.

The unisex design of the sneakers will potentially allow adults with larger or wider feet to more easily find a shoe that fits, with options going up to the equivalent of a size 15 for women. The ÜNOS by Sz will also be better suited for those with one foot that’s a half, or even a full size, larger than the other, saving them from having to buy two pairs to accommodate the discrepancy.

The sneakers were designed by Dr. D’Wayne Edwards, president of the business and design-focused Pensole Lewis College (PLC) in Detroit. The school describes Edwards as, “the most prominent Black designer in the footwear industry,” with a career that has included stints at L.A. Gear, Nike, and Jordan.

Speaking to Footwear News, Edwards said they’ve always wanted to design more affordable but high quality footwear. “Sometimes, when you see $50 and below product, it doesn’t have much tech, it doesn’t have much substance to it. I didn’t feel like $50 and below product needed to be that way.”
