Swalco will be on site to demonstrate how old gym shoes can be recycled into several materials. Quoting from the Hainesville website:
Please gather all your worn out, even falling apart or just too small gym shoes and bring them to the Fest to be turned into Nike Grind materials.
Please NO wet or excessively muddy shoes! No light ups (batteries), cleats or spikes.
Do cut out any metal eyelets or metal zippers. Shoelaces are fine; please have them untied.
If you have any “gently worn” dress shoes, slip-ons or gym shoes these will be collected for a donation to Share Your Soles
