I have a pair of Burton Fire shells in a MP 27.5-28.0 that are in good condition. They will fit 27.5mm to 28.4mm feet with the proper liners. I guess Burton boots fit feet narrow so that is also something to consider. Overall they are in good condition. There are scratches on them from use but all the buckles and plastics are in good condition. No cracks on them. The heels are brand new but the toe pads have some wear from use.
Pictures of them are located here: http://www.bogeydog.net/pics/album21
I am looking for $80 plus shipping. I think I can get them to the lower 48 for $15.
Please email me at ben -at- bogeydog -dot- net if you are interested in them.
Thanks,
->Ben
