Birkenstock's Boston mules will prove to be more versatile than you might first think - wear them in warmer seasons with shorts, switching to jeans and socks when the weather cools. They have supremely lightweight wool-felt uppers and are grounded by the brand's cork footbed that mimic the natural contours of your feet. Upper: Wool. Lining: Suede. Sole: Rubber.
