I am wondering if there are any shoe shopping sites comparable to zappos.com? Zappos is known for its shipping and return policy (both good) and everybody always raves. But they never seem to have some of the items I need (width, style, and brand). What are some stores known for their great service, but maybe have an even better variety? Zappos is trendy right now, but I want to go against the mold. Any suggestions would be appreciated. Thanks!
