Shoe Technology Explained
Know what you're buying before you spend $200 on a shoe.
Midsole Materials
EVA
Traditional foam. Durable, consistent, affordable. Hoka ProFly is EVA-based.
PEBA
Lightweight, super-responsive. Used in Nike ZoomX and Saucony PWRRUN PB. Less durable.
TPU
Bouncy, resilient. Great energy return. Used in Adidas Boost.
PEBA + Carbon
The performance combo: carbon plate + PEBA = maximum propulsion. Saucony Endorphin Edge, Hoka Tecton X2.
Outsole Rubber
Vibram Megagrip
The gold standard. Sticky on wet rock. Used by Hoka, Topo, Inov-8.
Contagrip
Salomon's proprietary compound. Excellent all-conditions grip.
FriXion AT
La Sportiva's mountain rubber. Outstanding on wet alpine rock.
TrailTack
Saucony's sticky compound. Great versatility on mixed terrain.
Plate Systems
Carbon Fiber
Stiff, propulsive. Helps push-off efficiency. Great for uphills (Hoka Tecton X2).
Nylon Rock Plate
Flexible protection from sharp rocks. Standard in technical trail shoes.
No Plate
More natural ground feel. Suitable for non-rocky terrain or minimalist runners.
Race Regulations
Some races have stack height limits (UTMB: 40mm max). Check before race day.
Drop & Stack Height
0mm (Zero Drop)
Heel and forefoot at same height. Promotes midfoot strike. Altra signature.
4–6mm
Low drop. Balance of natural feel and transition ease. Common in Hoka trail shoes.
8–12mm
Traditional drop. Familiar for road runners. Easier transition from road shoes.
Transitioning
Going lower in drop? Reduce by 2–4mm at a time. Give your calves 6+ weeks to adapt.
Shoe Rotation Strategy
The best ultra runners don't train in one shoe. A 3–4 shoe rotation extends lifespan, reduces injury risk, and matches the right tool to the workout.
Easy / Long Runs
Max cushion shoe
Protect your legs on high-mileage days. Comfort over speed.
e.g. Hoka Speedgoat 6
Workouts / Tempos
Lightweight racer
Responsive feel encourages proper form at faster paces.
e.g. Salomon S/Lab Ultra 3
Technical Trail
Technical specialist
Match grip to the terrain. Don't fight the trail.
e.g. La Sportiva Bushido III
Recovery Runs
Plush trainer
Fresh midsole = fresh legs. Let yesterday's shoe recover too.
e.g. Altra Olympus 5

Shoe Fitting Guide
A shoe that doesn't fit right will ruin your race. Get sizing right before training starts.
Sizing for Ultras
- →Go up 0.5–1 full size for races over 50 miles
- →Feet swell up to a full size on long runs
- →Thumb's width between longest toe and shoe tip
- →Try on shoes at the end of the day (feet are largest then)
- →Wear your race socks when fitting
Width Considerations
- →Altra: naturally wide toe box in regular width
- →Salomon: runs narrow — size up or go wide
- →Hoka: medium width, wide option available
- →Signs too narrow: black toenails, blisters on ball of foot, cramped toes
- →Signs too wide: heel slip, blisters on heel
Break-In & Retirement
- →Never race in brand new shoes
- →Allow 50–100 miles of break-in before a big race
- →Trail shoes: replace at 250–400 miles
- →Press test: push thumb into midsole — if it bottoms out easily, replace
- →Increased aches or joint pain = worn-out midsole
