I have 4 pairs of onesole shoes (www.onesole.com) with at least 12-15 interchangeable tops. Wedge soles, 3 1/2 inch spike heels, black, brown & cork. They are made in the USA of all man-made materials. They are the most comfortable sandals I have ever worn AND so lightweight so perfect for making sure you have shoes for every outfit without exceeding the luggage weight restrictions. . .
