If you love shoes and have several hours to spare (this last point is key), head to the annual Shoe-Inn, where you can find everything from UGGs to Chloe—there are over 7,000 pairs for you to sift through. Boots are $39.99-$249.99, shoes are $19.99-$99.99, and new stock is added daily. In the past, everything has been sorted by size and piled on tables several boxes deep (hence why I recommend clearing several hours). 1/4-1/8; 9-7 weekdays, 10-5 weekend; 1356 Broadway (at 36th St.).
