I am currently playing in a pair of Head Prestige shoes and I really love them. I bought them June 1st and they are supposed to have a 6 month guarantee. It has now been 4 months and I have worn the toe almost completely through and the soles are pretty bare. Does anyone know who I need to contact to send them back and how worn the shoes will need to be in order to get a new pair? I have sent back Barricades before but never Head shoes.
