The Boot vs Trail Shoe Debate

Footwear research and hiking safety guidance point to fit, traction, pack load, terrain, and conditioning as the variables that matter most. Mid-cut boots can help under heavier loads or rough ground, but trail shoes can be reasonable for lighter day hikes when they fit well and grip the surface.

  • Day hikes, under 20 lbs: Trail running shoes or low-cut hikers
  • Day hikes, 20-35 lbs or rocky terrain: Mid-cut hiking boots
  • Multi-day, 35+ lbs: Mid-cut or high-cut boots with stiff midsoles
  • Mountaineering or snow: Full-shank boots (different category)

Waterproofing: Misunderstood

Gore-Tex keeps water out but traps heat inside. In warm conditions (50°F+), non-waterproof mesh dries faster. REI's trail team recommends waterproof primarily for cold weather and wet climates.

  • If it still hurts after 50 miles: wrong boot. Return it.

Frequently Asked Questions

Do I need hiking boots or hiking shoes?

Hiking shoes (low-cut) are lighter and sufficient for day hikes on maintained trails with light loads. Boots (mid/high-cut) provide ankle support and stability for heavy packs, rough terrain, and multi-day trips. Most recreational hikers are fine with hiking shoes unless carrying 30+ lbs.

Should hiking boots be waterproof?

Waterproof boots (Gore-Tex lined) keep feet dry in wet conditions but run hotter and dry slowly if water gets in from the top. Non-waterproof boots are cooler and dry faster. For consistently dry climates, skip waterproofing. For variable conditions, waterproof is worth it.

How should hiking boots fit?

Try boots in the afternoon (feet swell). Wear your hiking socks. You should have a thumb's width of space in front of your longest toe. No heel slippage when walking uphill. Toes shouldn't hit the front when walking downhill. Break them in with 20-30 miles before a big trip.
