Footwear is the most personal gear decision in backpacking. There's no universal answer — but there is a right answer for your body, terrain, and pack weight.
The Core Tradeoff
| Factor | Hiking Boots | Trail Runners |
|---|---|---|
| Weight | 2-4 lbs/pair | 1-2 lbs/pair |
| Ankle support | High | Low-Medium |
| Break-in time | Long | Little to none |
| Waterproofing | Usually GTX | Rare |
| Durability | 500-1,000 miles | 400-600 miles |
| Drying time | Very slow | Fast |
| Cost | $100-300 | $100-200 |
The Case for Hiking Boots
Ankle support: Boots provide structure around the ankle, which matters most with heavy packs (30+ lbs) or on loose, rocky terrain.
Waterproofing: Gore-Tex lined boots keep feet dry in rain, stream crossings, and morning dew — within limits.
Durability: Leather and stiff rubber outsoles last longer on rocky trails.
Best for:
- Beginners who haven't built ankle strength
- Hikers with previous ankle injuries
- Heavy packs (30+ lbs)
- Technical terrain with talus, scree, or loose rock
- Multi-week trips where sole durability matters
The Case for Trail Runners
The ultralight community largely switched to trail runners 10+ years ago.
Weight saves energy: Every 1 lb on your feet equals ~6 lbs on your back in energy cost. Lighter shoes = less fatigue over miles.
Proprioception: Low, flexible soles let your foot feel the terrain, which actually improves balance and reduces rolls.
Wet feet: GTX boots keep water out — until water gets in over the top. Then they trap water for hours. Trail runners get wet and dry in 30-60 minutes.
Best for:
- Experienced hikers with strong ankles
- Lighter packs (under 25 lbs)
- Maintained trails
- Long-distance/thru-hiking
- Wet environments (they dry faster)
The Ankle Support Myth
Studies don't show that high boots prevent ankle sprains. What prevents sprains:
- Strong ankles (training)
- Lower pack weight
- Trail awareness
- Proper fit
Many thru-hikers report fewer ankle injuries after switching to trail runners — because the lighter weight reduces fatigue, which is when most rolls happen.
What to Look For in Each
Hiking Boots
- Full grain leather for durability on rugged terrain
- Crampon-compatible if you'll encounter snow or ice
- Stiff midsole for support on heavy loads
- Wide toe box — feet swell on long days
Trail Runners
- Lugged outsole (Vibram or similar) for grip
- Rock plate if your trails have lots of sharp stones
- Stack height — lower is lighter, higher is more cushioned
- Wide toe box — same as boots, critical for long days
The Break-In Question
Boots require 50-100 miles of break-in. Wearing new boots on a long trip = blisters.
Trail runners fit immediately. This alone converts many hikers.

| Hoka Speedgoat 5 | 1.8 lbs | Cushion, all terrain |
| Altra Lone Peak 7 | 1.6 lbs | Wide toe box, zero drop |
| Salomon Sense Ride 5 | 1.5 lbs | Fast, technical trails |
| Brooks Cascadia 17 | 1.9 lbs | Long miles, all-day comfort |
The Verdict
Wear boots if: You have a heavy pack, weak ankles, are doing technical terrain, or are new to backpacking.
Wear trail runners if: You have a light-to-moderate pack, strong ankles, and prioritize comfort over long miles.
The trend: Most experienced backpackers move to trail runners as their packs get lighter. It's not a question of if — it's when.
