Updates to Vibram FiveFingers Trek Ascent

  • Vibram introduced the Trek Ascent with a 4mm Megagrip rubber outsole for exceptional traction and durability. The underfoot features multi-directional lugs for grip on different surfaces. With a 4mm thickness, it should be able to provide excellent ground feedback with enough protection against rocks and sharp objects.
  • A high cuff is also part of the feature in this shoe. The cuff serves as a barrier that prevents debris from getting inside the shoe.
  • In lieu of standard laces, Vibram utilizes speed laces for quick and effortless cinching. The laces stay as it is from the start of the run until the end.
  • The polyester and Spandex upper provide optimal form-fitting fit that is also quite breathable. It fits like a second skin.

Size and fit

Based on Vibram’s website, the Vibram Trek Ascent runs a size smaller compared to their other shoes. The overall fit is snug and really sticks to the foot. There is decent forefoot space before the toe slots accommodate each of the 5 toes for excellent comfort and toe splay. Runners who are familiar with Vibram’s will easily recognize the fit provided by this shoe.


Outsole

Vibram’s proprietary rubber compound, the Megagrip, ensures a grippy performance by the FiveFingers Trek Ascent on the trails. In addition to this very sticky compound, the entire outsole is covered with multi-directional lugs from the heel to the toes for traction and leverage. The whole 4mm rubber is exceedingly flexible and should aid the runner’s natural running movements with adequate protection against the rugged terrains.


Midsole

There is technically no midsole in the Trek Ascent. A 4mm EVA insole with Dri-Lex anti-microbial features handle a little of the cushioning and more underfoot protection. It has sufficient responsiveness and cushioning that will not impede the barefoot runner’s need for ground feedback.


Upper

The really minimalist upper of the Vibram FiveFingers Trek Ascent is made of Spandex and polyester for that snug, but breathable and comfortable fit. A speed lace allows for easy cinching and relatively personalized fit. The high cuff serves as protection against dirt, dust, and trail debris when running the trails.
