Mohop, the eco-friendly, customizable line of sandals Annie Mohaupt founded in 2005, has enjoyed enviable success in a competitive industry and a brutal economy. Since their debut, the sandals have been regularly covered in a slew of local as well as national publications, and last year designer Behnaz Sarafpour asked Mohaupt to create shoes for her spring 2011 show at New York Fashion Week. To meet the demand for the handmade designs, Mohaupt often ended up sleeping at her studio—up to three times a week—to maximize time spent sawing plywood, applying finishes and rubber soles, and molding them into shape.
