My competitive running career has come to a close (several times over) and I have 8-10 pairs of spikes that are used but still have plenty of races left in them. Are there any organizations/charities out there that actually redistribute used shoes/spikes to athletes in need? They are all relatively "new", mostly 2012-2014 models of Nike and Adidas spikes. I'd hate to throw them away or donate them to an organization that just recycles them for the materials etc..
