NWT Madewell "Size 9.5" THE BOARDWALK CHUNKY THONG SANDAL tan leather comfy flat Big news: We gave fan favorite Boardwalk sandals a foot-friendly makeover with a touch of comfy padding (so you'll want to go everywhere in them). With their boldly chunky leather straps, these modern thongs are a definite flip-flops upgrade. Please note: This sandal runs small, so I recommend ordering a full size larger than your normal size. Leather. Man-made sole.
