See that sleek little gray tube in your clutch? It might be more indispensable than your gloss. It’s Sidewalk Skincare, and later today (or tonight) the nongreasy balm is going to heal your love-hate relationship with your fave pair of shoes. Just slick it on heels, toes, or whatever else needs protection against annoying chafing and blisters. Created by Jody Llewellyn after she ran an NYC marathon, the paraben- and synthetic fragrance-free formula is made with beeswax, lavender oil, and dandelion extract to help soothe and repair. After road testing Sidewalk Skincare on a particularly uncomfortable pair of flats, our feet stayed soft and blister free. It’ll also help keep stubborn bra straps from digging into your shoulders. And we really dig that.
