Sporting a cool pair of shoes can be a transcendent experience for the style-obsessed, grandtoddlers included — but if they're stiff and uncomfortable, the fashion show is over. When Polish shoe designer and new dad Slawomir Piwowarczyk saw the digging and blistering effects of the average shoe on his own toddler's feet, he set out to design the world's most perfect, unisex shoe for little walkers: the Gucio. It's a wide-set walking shoe made of extra soft and flexible leather that molds to kids' feet and a seamless interior that severely limits any chafing. Following the golden rule of great design, style and function are equal here, defending your grandchild's title of playground’s hippest.
