Designed for Running and Training. Our shoes use US sizing and run small. To find your fit, measure your foot from heel to toe in cm and check it against the US size in our size chart. Those with wide feet should consider going up half a size. Chargefeel 3 is a hybrid running and training shoe with a responsive, balanced feel. Run faster. Train harder. The Chargefeel 3 delivers adaptable performance for any way you work out. | lululemonWomen's Chargefeel 3 Workout ShoesColor Black/GreenSize 12
