Frequently Asked Questions
Will my heel actually feel stable, or wobble around?
The KEEN.LOCKFIT firm U-shaped support is built specifically to hold the heel in place for extra stability.
Will these actually feel lighter on my feet than a typical work boot?
Yes, this is one of KEEN's lightest waterproof work boots.
Is the Synchro waterproof?
Yes. A KEEN.DRY waterproof, breathable membrane seals out water while letting moisture escape, and the upper carries a PFAS-free durable water repellent finish.
What protection does the Synchro's carbon toe provide?
The Synchro has a 100% non-metallic carbon safety toe for impact and compression protection, a heat-resistant rubber outsole rated to 572°F (300°C), and a rubber tread built for traction.
How does the Synchro fit?
It runs true to size — order the size you wear in athletic shoes. Keen's toe box is roomier than most work boots, and the KEEN.LOCKFIT heel support holds the heel in place, so size on length rather than up.
How do I care for the Synchro?
Knock off dirt, wipe the leather clean, let the boot dry away from direct heat, and condition the leather every few months. Cement construction is not resoleable, so rotate pairs to extend the outsole.
