Keen Targhee 4S Hiking Boots Review: Key Upgrades & Fit Analysis

content: First Impressions After Replacing Old Boots

Switching hiking boots always feels significant, especially when upgrading from worn-out gear. Having tested the Keen Targhee 4S after extensive use of previous models, I immediately noticed substantial design evolution. Unlike traditional hiking boots, these prioritize toe comfort without compromising protection. For those seeking durable all-terrain footwear, understanding these upgrades is essential before investing.

Key Differences From Previous Generations

The Targhee 4S shifts toward a robust yet flexible construction. While retaining Keen's signature ankle support, the reinforced toe cap and heel counter are noticeably more substantial. This addresses the common wear points that degrade lesser boots over rocky trails. Premium full-grain leather dominates the upper, promising longevity where synthetic materials often fail.

Waterproofing and breathability often work against each other, but Keen's proprietary membrane handles this balance effectively. During creek crossings and humid climbs, my feet stayed dry without overheating—a crucial advantage for multi-day hikes.

Game-Changing Toe Box Design

The generational toe box redesign stands as this model's breakthrough feature. Unlike narrow competitors causing blisters on descents, the spacious front end allows natural toe splay. This prevents numbness during long approaches and enhances stability on uneven terrain. If you've struggled with cramped footwear before, this innovation alone justifies consideration.

Weight and Value Assessment

At 650g (size UK 8), these boots sit in the midweight category. They’re lighter than full-leather mountaineering options but offer comparable protection. For their £155 RRP, you gain:

  • All-condition readiness (mud, rock, wet grass)
  • Abrasion-resistant leather
  • Strategic cushioning in high-impact zones
    Industry data shows boots in this weight class typically last 800+ km with proper care, making the cost per kilometer highly competitive.

While the wide toe box benefits most users, those with narrow feet should try before buying. The break-in period proved shorter than typical premium boots—about 20km of trail use eliminated initial stiffness.

How These Compare to Market Leaders

Compared to Salomon Quest 4 or Merrell Moab 3:

  • Targhee 4S wins on toe room and toe protection
  • Salomon leads in precise heel lockdown
  • Merrell offers lighter weight for fastpacking
    This positions the Keens as ideal for backpackers carrying heavy loads where foot expansion occurs.

Before purchasing, complete this checklist:

  1. Measure your feet at day’s end when they’re swollen
  2. Test with hiking socks you’ll actually wear
  3. Walk on inclined surfaces in-store
  4. Check clearance between longest toe and boot end
  5. Verify arch support matches your foot shape

Why I’ll Be Using These All Season

Having hiked in everything from trail runners to mountaineering boots, the Targhee 4S strikes a rare balance. They deliver rugged protection without punishing rigidity, and the toe space eliminates downhill agony. While no boot fits every foot, these solve key pain points for mid-to-wide-footed hikers tackling variable terrain.
