Updates to Altra Lone Peak 4.0 RSM

  • The Altra Lone Peak 4.0 RSM is a trail running shoe that’s designed for the neutral runner. The RSM in its name signifies the Rain, Snow and Mud specialty of the Altra All-Weather Series. Such a distinction is indicative of the presence of a waterproof upper and a highly aggressive outsole configuration.
  • Most of this off-road companion’s features focus on protecting the foot from abrasion and encouraging surface control through the trail-ready features of the sole unit. But underfoot comfort is also a primary purpose, with multiple technologies working together to ensure comfort and energized performance.

Altra Lone Peak 4.0 RSM size and fit

The Altra Lone Peak 4.0 RSM was crafted using the standard measurements. When it comes to size, runners can choose a pair with their usual sizing preferences in mind. Widthwise, the available options are D – Medium and B – Medium for men and women, respectively. The foot-shaped last accommodates the natural curve of the foot, as well as regular toe-splay.

Outsole

MaxTrac™ is a thick rubber compound that covers the rest of the platform. The purpose of this component is to protect against abrasion and to provide a sure grip over the terrain.

The TrailClaw™ configuration involves opposite-facing gripping lugs that are responsible for gripping the ground. These protrusions heighten movement control during ascents and descents. The base of the metatarsals even contains anatomical nodes for extra support and handling.

Midsole

A-Bound™ is a full-length cushioning unit that carries the foot throughout the running session. It is made using recycled materials, making it a compound that is friendly to the environment.

EVA is an industry-standard material that attenuates shock and encourages flexible support. It can withstand sagging or breakdown.

A protective layer called StoneGuard™ is placed between the A-Bound™ and the EVA foam. The goal of this add-on is to prevent sharp trail debris and surfaces from hurting the underside of the foot.

An even underfoot experience is the responsibility of the Zero Drop™ Platform. Such a design encourages natural foot balance and well-rounded impact dispersal when taking each step.

Upper

The Altra Lone Peak 4.0 RSM makes use of the eVent®, which is waterproof. Its job is to completely stave off water infiltration while maintaining breathability.

The 4-Point Gaiter Trap™ involves stitched and fused overlays that accommodate protective attachments and garments. This system further protects the interior chamber of this shoe from wetness and debris.

The FootShape™ Toe Box is a spacious forefoot section that permits the natural splaying of the toes. This layout potentially improves balance and control over the uneven topography.
