Downhill shear
Where gravity works on your toes.
Sustained descents pulled straight from the elevation profile. Pretape before these, not after.

When the shoe stops drying out.
Modeled across the cutoff window from 7 years of race-date weather at points along the course.

Kit deltas
What Mogollon Monster adds to the standard kit.
- Powder and a moisture barrierSweat is the friction multiplier on this course.
- Pretape for toes and heelsLong descents load the front of the shoe and lift the heel.
- Extra dry socks and a towelCold wet feet break down faster than cold dry feet.
- Vest foot kit you can use aloneThe widest gap is long enough that a hot spot becomes a blister before the next station.
- Light you can tape byTaping in the dark with cold hands is a different skill than taping at your kitchen table.
- Half size up in the crew bagFeet swell over the back half. A tight shoe at midnight ends races.
- Moleskin for pressure pointsRock strikes and side loading build hot spots off the usual map.
Shoes
What survives this course.
Matched on terrain, technicality, and distance. Fit still beats every spec, so try them on a long run first.
Crew
What your crew needs on paper.
Two plates. On the left, the race-specific notes that never make it into the standard script. On the right, the printable card your crew reads at two in the morning under a headlamp.
Race day notes
- The Highline Trail is loose rock, roots, and constant foot correction. Bruising matters as much as friction here.
- September in Arizona still reaches the mid eighties on the exposed rim sections.
- Educational only. Test every tape, sock, and shoe combination on long runs before race day.

FAQ
Mogollon Monster foot questions.
- 01
Where should I stop for foot care at Mogollon Monster?
Fish Hatchery at mile 27.1. Those stops carry the most ground and descent behind them, so a sock change and a tape check pay for the minutes they cost.
- 02
Which section of Mogollon Monster wrecks feet?
Mile 22 to 29.5 drops 1,700 ft at 4.3 percent average grade. That is where toes meet the front of the shoe and heels start to lift. Pretape before it, not after.
- 03
How do I keep my feet dry at Mogollon Monster?
September highs reach 85 degrees F. Sweat saturates socks, skin softens, friction climbs. Change socks at every stop you can, run powder or a moisture barrier, and lean forward when you dump water on your head so it misses your shoes.
- 04
Do I need dry socks for the cold sections of Mogollon Monster?
Lows near 35 degrees F. Wet feet plus cold is how trench foot and numb toes start. Put a dry pair in every bag you will see after dark and warm your feet before you tape.
- 05
How many sock changes for Mogollon Monster?
Plan one at every foot stop you have access to, and carry one spare pair beyond that. 100 miles inside 38 hours is long enough that dry socks are faster than the five minutes they cost.
- 06
What goes in my vest for Mogollon Monster?
12.5 miles between stations at the widest gap. Carry what you need to fix a hot spot alone. Tape, two wipes, a blister patch, and a small tube of lube covers a hot spot without waiting for crew.
- 07
How do I stop blisters at Mogollon Monster?
Start from the biggest threat on this course. 100 miles inside a 38 hour limit. Every hour adds shear, swelling, and sock saturation. Fit the shoe with room for swelling, pretape the spots that have blistered on you before, keep grit out, and change socks at every stop you have access to. Blisters come from pressure, friction, and moisture, so remove whichever one this course hands you the most of.
- 08
What foot care kit should I pack for Mogollon Monster?
Beyond the standard kit, this course calls for powder and a moisture barrier, pretape for toes and heels, extra dry socks and a towel, vest foot kit you can use alone, light you can tape by, half size up in the crew bag, moleskin for pressure points. Sweat is the friction multiplier on this course.
- 09

75% trail / 20% jeep / 5% paved at technicality 9/10 points toward Nike Zegama Trail, Norda 055, Brooks Cascadia 19. Whatever you pick, race it on a long run first and leave room for feet that swell over the back half.
