Sturdy and well-made. Nice, firm sole but pliable soles for good traction. Stylish, too... my daughter gets compliments on them all the time, but we've never seen them on anyone else. We'd been buying Keens for the past year, but we've become rather disenchanted with that brand and these Adidas have replaced them as the play-show staple in my two-year-old's "wardrobe". Highly recommend.
