Mason Moto Biker Engineer Boots Chippewa Falls USA Made Men's SZ 8.5 C Black. Pre-owned good condition with normal signs of use observed. I believe these to be vintage 1980s, possibly older. The Mason shoe factory in Chippewa Falls closed in 2003 just short of the 100th anniversary. Cool as hell!!! These are everything! Solid leather construction, soft toe, Armortred soles, broken in nicely with a timeless and classic cool look that transcends decades. Get your rebel look right here. Packed and ready for their new home. GenX approved! Please see the images for a complete visual description of the condition, as I try to document all flaws observed, if any. I try to ship FAST! Usually within 24 hours of payment. UPS Ground. Sold as is. All sales are final. Shipped & Packed securely using recycled and re-purposed materials whenever possible. Thanks for checking out my cool finds!
