Vibram® Sole Capabilities Merrell uses Vibram® soles on more than 75% of its hiking, multi-sport and trail running styles. Merrell/Vibram® soles showcase all of Vibram’s® design capabilities:

  • Sharply angled braking studs and an under cut heel for descending.
  • Multi-directional, “S”-shaped thrust studs for climbing.
  • No lugs in the arch so the foot flexes naturally.
  • Highly slip-resistant “Yellow Label” Trek Compound rubber—the perfect chemical combination for stickiness and abrasion resistance.

Trek AND TC5+ Rubber Compounds Vibram’s® Trek and TC5+ rubber compounds represent breakthrough technology in grip, stability and abrasion resistance for hikers. Numerous tests in the lab and in the field have confirmed this compound as being the best on the market.

  • GRIP—Excellent grip on dry and wet ground.
  • WEAR—The wear resistance of Trek and TC5+ rubber guarantees long life for the sole and its technical features. Abrasion and tear resistance are also excellent.

Behavior at High and Low Temperatures Trek and TC5+ rubber performs consistently in varied weather conditions, maintaining its original traction and slip resistance in a wide range of temperatures, hot or cold.

Resoleable You can replace some Vibram® soles when they wear out to extend the life of your boots.
