I have a pair of Deeluxe spark boots size 10 from last year. The mold i had done on the liner did not fit me well so I rode my old drivers for most days. I would say the boots have about 30 days on them and less on the liners because i used my old Burton liners in the spark boots too. The liners have full life left in them and can be remolded.
