Ask any infantry veteran what they were taught to protect first and the answer isn’t their knees or their back — it’s their feet. Foot care is mission care, and the medical literature backs the tradition: military personnel are consistently identified among the populations where athlete’s foot is most common¹, alongside athletes and people who work long shifts in boots. The reasons are built into the job — and so, fortunately, is the fix: a daily prevention habit that takes less time than lacing up.
Why military feet are a perfect storm
- The boots. Occlusive footwear worn 12–16 hours is the defining risk: warmth, darkness, and trapped moisture are precisely the conditions the fungus needs to grow², and a combat boot supplies all three from first formation to lights out. Unlike an office worker, a soldier can’t take their boots off mid-shift.
- The sweat. Feet carry the densest sweat glands on the body — 250 to 500 per square centimeter on the soles³ — and heavy exertion under load multiplies output. Sixteen hours of that inside a boot is a fungal greenhouse.
- The shared everything. Barracks showers, gym floors, communal latrines — communal bathing facilities are a major epidemiologic risk factor for athlete’s foot⁴, and unit life runs on them. One case on a floor becomes the floor’s case.
- The demographics. The infection is most common in adults 15–40 and prefers males⁴ — a description of the active-duty population almost exactly.
- The field. Deployments and field exercises add wet socks with no laundry, boots that never fully dry, and hygiene on the clock. Recurrence is common in the best conditions² — these aren’t the best conditions.
The daily prevention habit: an antifungal, before there’s anything to treat
Tolnaftate 1% — the active ingredient in the Dryello® Athlete’s Foot Treatment Stick — is recognized for the treatment of most athlete’s foot and, with daily use, to help prevent it. That prevention indication is the whole strategy for a high-risk population: one dry swipe across each foot before socks go on maintains an antifungal barrier on exactly the skin the barracks shower and the boot keep attacking. You don’t wait to get hit; you patrol. Explore the Athlete’s Foot Treatment Stick
The format matters in a kit. The stick is compact and dry — no tube of cream to burst in a ruck, no powder cloud in shared quarters, no touching your feet with your hands, and it weighs next to nothing. As one 17-year Army infantry veteran who introduced Dryello® to fellow soldiers put it: when you’re deployed, ounces turn into pounds — a small stick earns its place in the kit. And if an infection does take hold: the same stick treats it. In Dryello®’s clinical studies, 87% of participants were mycologically cured — no detectable fungus — after 4 weeks of twice-daily use (2 cohorts aggregated, per-protocol; n=39 at 4 weeks).* Complete the full 30-day course, then return to daily prevention.

Hot spots: the other war your boots are fighting
Every ruck march tells the same story: moisture builds inside the boot, damp skin softens and drags against the sock, friction concentrates at heel and forefoot — and a hot spot becomes a blister becomes a limp. That’s where the second stick earns its slot: the Dryello® Antiperspirant Deodorant Foot Soft Glide Stick helps cut sweat at the source — over 30% sweat reduction at Day 14 in a 2026 clinical efficacy study* — and a benefit users consistently report is less friction and fewer hot spots inside their boots. Drier skin slides less. For anyone who measures their days in miles carried, that’s not a comfort feature; it’s an endurance feature. It’s also skin-health common sense: friction micro-damage gives fungus an easier way in² — one more reason to keep skin dry and intact.

The field-tested routine (two minutes, twice a day)
- Morning: clean, dry feet → antifungal stick (prevention) → antiperspirant stick if sweat and hot spots are your pattern → moisture-wicking socks. Thirty seconds to dry, boots on.
- Every chance you get: socks off, feet dried — especially between the toes — fresh socks. Carry spares; change them like it’s doctrine, because it is.
- Night: wash, towel-dry thoroughly, second antifungal application, and pull the insoles so boots can actually dry. Rotate pairs when you have the option — boots need 24+ hours to dry fully.
- Always: shower shoes in communal showers⁴, your own towel, your own stick — fungal infections travel by contact.
Built by people who get it
Dryello® is a product of Propedix, a veteran-led company — CEO Niv Caviar is a U.S. Air Force Academy graduate and Air Force veteran — founded by Dr. Carl Schanbacher, a board-certified dermatologist who built the first dry stick antifungal for exactly the people who can’t take their boots off mid-shift.
