Volkl Wall, Sth, SPK

I have a pair of 169cm Volkl Walls with Salomon Sth bindings. I also have Salomon SPK boots size 28.5. I am leaving for Telluride CO on Jan 3, 2015 (2 days from now). I am hoping to sell the skis and buy a pair of better fitting boots, tried some full tilts last year and liked them. Anyone in the Denver or Telluride area looking to sell their boots? I need something closer to a 27.5. Thanks for looking and any help on the issue will be appreciated.
