Timberland PRO BOA® Boondock 6" Composite Toe Waterproof Work Boot — Medium Brown Full-Grain — TB0A66KYEM4
The heavy-duty Boondock in a 6" cut, with the BOA® Fit System for a fast, micro-adjustable, precision fit.
Timberland PRO designed the Boondock to provide industrial-grade protection from every angle: a premium full-grain waterproof leather upper with an internal waterproof, breathable membrane, a molded rubber toe protector backed by a composite safety toe, a rigid external heel cup, a non-metallic puncture-resistant plate, and the Anti-Fatigue Technology footbed — all on a lightweight All-Weather TPU outsole. The BOA® M4 dial replaces laces for a fit that stays put all shift.

Dialed-In Fit, No Laces to Fail
The BOA® M4 dial tensions a braided stainless-steel lace through nylon guides, so you can tighten or release the whole boot in seconds with gloves on. There are no laces to fray, ice up, or come untied, and the tension is even across the instep rather than concentrated at the knots.
Puncture, Impact, and Electrical Protection
A composite toe and rubber toe guard up front, a non-metallic puncture-resistant plate underfoot, and an EH-rated, electric-shock-resistant sole — the full Boondock protection package in a lighter 6" cut. The plate, toe, and shank are all non-metallic.
Why a 6" Boondock
The 6" shaft gives you full Boondock protection with more ankle mobility and less weight than the 8", which suits warehouse, manufacturing, and site work where you are moving all shift rather than wading through debris.
Why Choose the TB0A66KYEM4?
A waterproof, puncture-resistant, EH-rated composite-toe Boondock with a BOA® dial fit in a mobile 6" cut — the pick for industrial sites where you want maximum protection and a fit you can adjust in seconds.

Frequently Asked Questions
What safety certifications does the BOA® Boondock 6" carry?
An ASTM F2413-rated composite safety toe, a non-metallic puncture-resistant plate, electrical hazard protection, and an electric shock resistant (ESR) sole — one of the most complete protection packages in a 6" boot.
How does the BOA® Fit System work?
Turn the M4 dial to tension a braided stainless-steel lace through nylon guides; pop the dial out to release. It works with gloves on and holds even tension across the instep all shift.
What if a BOA® dial or lace is damaged?
BOA® guarantees its dials and laces for the life of the footwear and ships replacement parts at no charge through its warranty program, so a damaged dial does not retire the boot.
Does the Boondock run true to size?
The Boondock is built on Timberland's TiTAN® last, which most owners find true to size with a roomy toe box. Order the size you wear in athletic shoes; the BOA® dial takes up any slack in fit.
Can the Boondock be resoled?
Yes. The three-quarter Goodyear® welt stitches the outsole to the upper through the forefoot, which is the section a cobbler rebuilds; the cemented heel keeps the boot lighter and more flexible out of the box.
Is this boot insulated?
The TB0A66KYEM4 is a waterproof, uninsulated three-season boot built to breathe while you move. For cold-weather work, the BOA® Boondock 8" TB0A67B3W02 adds 400 grams of insulation.
