The supremely comfortable, amazingly light, all-purpose Drift is an espadrille slip-on that can also be worn as a clog. Featuring the unique SoftScience Trileon footbed and insole technology, coupled with breathable woven microfiber upper, our signature shoe is easy-to-wear, relaxed and can reduce foot discomfort. If you are on your feet all day, you will appreciate this new dimension in comfort. It is also the perfect "after-anything shoe" â after sports and exercise, after work, after surgery â indoors or out. SoftScience shoes are designed and engineered to provide a roomy and generous fit. Their shoes come in whole sizes only, so if you normally wear a 9.5, choose your SoftScience shoe in a size 10. This generous fit feels secure, but not snug, and allows for breathability, ventilation and healthy foot circulation to keep you comfortable.
