A Boot First. A Sneaker Second.
Danner didn't get its start building athletic shoes — it makes boots. So when the team set out to build a lightweight trainer, they used over 90 years of bootmaking experience to create a boot that acts like a shoe, not a shoe that acts like a boot. The Tachyon is Danner's lightest, most flexible boot ever, built for training and special operations.
