I have 2010 Ronix Reflectos that I wore last summer in awesome conditions. THere 11s. I still have the box, red bull shot and parks documentary. They were $500 new, I have no idea what theyre worth used.
resale value on used gear is not very good. I'd say $200 tops maybe less depending on how many times they were used. I was only able to get $250 for a pair of 2010 LF vantages last year. Retail was like $450 and they were worn once. good luck.
