This year the event has partnered with Heeling Soles, a charity that provides new or gently used sneakers to the feet of those in need. Heeling Soles is asking attendees for donations; each attendee who brings a pair of sneakers will not have to wait on line.

Contests, giveaway and raffles will be taking place throughout the day. For more information, visit the website.
