Altra Instinct 3.5

The Instinct 3.5 retains its lightweight, flexible design and innovative technology that put Altra on the map. This updated trainer is back with a new look, soft upper, and more responsive ride. The FootShape toe box allows the foot to relax and spread out naturally, and keeps the big toe straight for more power. FootPod outsole technology maps the bones and tendons of the foot for natural flexibility and more responsiveness. The flexible, max-cushioned Zero Drop platform places your foot in a natural position for an efficient, stable, and fast running experience. A top layer of A-Bound energy-return compound puts a spring into each step, while the EVA foam beneath it protects your feet. Lace up into this update and power through your next run with the new Instinct 3.5 from Altra.

Features

      
  • Altra-suggested uses: running, ultramarathons, long distance walking, cross training
  • Designed to improve: running form, toe splay, stability, power
  • Quick-Dry Air Mesh upper with improved fit
  • Advanced 6-mm contoured insole features traditional molded arch and heel wrap
  • FootShape toe box allows the toes to relax and spread out naturally. This reduces over-pronation, enhances stability and creates a powerful toe-off to maximize running performance
  • Fully cushioned Zero Drop platform places the heel and forefoot the same distance from the ground
  • Zero Drop platform naturally aligns the feet, back and body posture which encourages a low-impact landing and strengthens the Achilles and lower calf muscles
  • Dual-layer midsole is made of EVA with an A-Bound top layer and InnerFlex
  • A-Bound is an environmentally friendly energy-return compound that is positioned directly under the foot offering extra protection. It returns energy with each stride and reduces impact of hard surfaces while maintaining ground feedback
  • A-Bound compresses less than traditional running shoe foam so it won't deform over time
  • Natural Ride System (NRS) is a unique combination of outsole and midsole componentry with proper metatarsal parabola
  • Zero Drop platform and FootShape allows runners to run as nature intended
  • FootPod outsole maps the bones and tendons of the foot for a natural flex and superior traction

Altra Fit

To maximize the benefits of Altra Footwear, we encourage you to follow these fitting suggestions:

  • Please allow at least ½ inch between the longest toe and the end of the shoe
  • Zero Drop footwear should feel as relaxed and natural as possible
  • If fit is correct, it may feel "too loose" around toes and may take a day or two for feet to get used to spreading out
  • Fitting this way will allow feet to become more stable, more comfortable and more powerful

  • Type: Structured
  • Manufacturer's Category: Neutral / Moderate Cushioning
  • Pronation Control: Neutral
  • Weight: 8.1 oz
  • Height: 24/24 mm (Heel/Toe)
  • Drop: 0 mm
