  • Soles: High traction, abrasion resistant, oil, flame, and chemical resistant, nitrile rubber outsole equipped with ergonomic HeelRoll and ToeSpring to promote a natural walking motion. Mountaineering lug design provides maximum traction. Multi-directional lugs provide sure-footed edging, braking, kickoff, and stability. High profile ladder grips for gripping on roots, branches, sticks, stones and, of course, ladders. Specially formulated compound (nominal durometer 66 Shore A) provides superior traction without sacrificing abrasion resistance or durability. Welted construction allows for sole replacement.
  • Sole attachment: 2 component, high temp polyurethane adhesive system bonds the outsole to the midsole then the sole is stitched to the midsole in forefoot area with tough, thick, fire-resistant Kevlar® thread.
  • MidsoleArmor: a unique and innovative integrated lightweight midsole design combines the functionality of the midsole, ladder shank, and puncture protection into a single component. The combination composite anti-puncture plate / ladder shank / midsole provides full puncture resistant coverage and thermal insulation for the bottom of the foot. This Cosmas® exclusive, patent-pending construction is stiff and supportive in the heel and arch, yet flexible in the forefoot, allowing your foot to flex naturally. Combining 3 functions into one component saves weight and bulk.

The Boots:

Here's the story behind these revolutionary wildland fire boots. Lots of wildland fire fighters in the US and Canada have started wearing mountaineering / hiking / backpacking boots instead of traditional logger boots. The hiking / mountaineering boots are designed for the type of work they do all the time... climbing hills and mountains while carrying heavy gear.

The problem was that the standard mountaineering / hiking boots were great for the task but lacked safety features needed while fighting wild fires. Cosmas stepped in with a revolutionary boot based on an update to traditional mountaineering boot design. That initial boot design was fire tested in the field then modifications were made to the original design based on feedback from wildland fire fighters who spent a season wearing the first design. The result was the current Hercules V2 boot which is a bit higher than the original, has a one piece upper design and incorporates many suggestions from wildland firefighters. It has been very well received and we're proud to be carrying this boot.

If you don't have any fires to fight, you'll find that this is a great boot for general purpose hiking, backpacking and mountaineering. Not many hiking boots are available in this range of sizes and widths and at this great price.

How They Fit:

These boots are designed to fit accurately when worn with standard boot socks. So they match the standard US men's sizes. Unlike many fire boots, particularly traditional rubber boots, these are not loose and sloppy in their fit. Cosmas does not add extra room to the sizing. Our advice for fitting these boots is to measure your feet to determine your US men's foot size then pick a boot in that size.

They don't include extra room to make them larger than sized. So, if there's any uncertainty on the size to pick, go up a half size. Some customers say the boots feel slightly small when new (maybe ½ size) but they usually find the fit to be just right after the boots are broken in a bit.

This is typical with any boots which have a padded lining like these do.

If you normally wear extra heavy boot socks, (or multiple pairs but not counting thin polypropylene, CoolMax or silk liner socks) you should go up ½ size from your US men's foot size when you order. In our wear testing we've found these boots to work well and fit comfortably when worn with standard boot socks.

Finally, we advise that you always avoid cotton socks. See our FAQ discussion about socks here.
