What are the perks of the "Smerk"? Too many to count! The Madden Girl Smerk Black Strappy Flat Sandals take black twill and frame a petite peep toe with lots of tiny toe straps. Two more straps crisscross the vamp, meeting as a wraparound ankle strap that adjusts with a gold buckle. 1/4" rubber heel has non-skid markings. Lightly cushioned insole. Non-skid felted rubber sole. Available in whole and half sizes. Measurements are for a size 6. All vegan friendly, man made materials.
