Updates to Adidas Terrex Two BOA

  • The Adidas Terrex Two Boa is an update of an update, utilizing minor changes that aim to significantly change the way the runner experiences the product in conjunction with the running session. The highlight is the Boa® Fit System, an adjustment method that involves stretchy cables and a twist-and-lock knob.
  • Underfoot cushioning is the responsibility of a full-length ethylene vinyl acetate (EVA) foam. This unit is touted to have a slightly thicker structure than the original Terrex Two model while retaining a lightweight build. Continental™ rubber shields the base of the midsole form the abrasive nature of the ground.

Size and fit

The standard sizing scheme is used during the creation of the Adidas Terrex Two Boa. Runners are welcome to use their usual choices when it comes to deciding on getting a pair. Still, it is important to test the shoe first or read user reviews from various sources.

The fit is affected by the upper unit’s form-fitting design, the midsole’s semi-curved shape, and the relationship of the shoe’s features with the shape and structure of the wearer’s foot. The Terrex Two Boa tries to accommodate the natural curvature of the foot by having an anatomical lasting board.


Continental™ rubber serves as the outsole unit of the Adidas Terrex Two Boa. This compound protects the midsole from the potentially damaging nature of the ground, thus preserving the efficacy and form of the cushioning system. Rubber is also naturally grippy, so natural surface adhesion can be received from this shoe.

Heightened surface traction is given by the set of trail-optimized gripping lugs that are patterned across the external pad. These nodes, though clamp-like in shape, have flat ends to prevent the alienation of traversing on asphalt or groomed paths.


EVA or ethylene-vinyl acetate is a material that is lightweight, responsive and moderately flexible. It is capable of absorbing impact shock during the landing phase and energizing the foot during the toe-off part of the step. The piece used for the Terrex Two Boa is advertised to be a bit thicker than the one in the original model. Many running shoe series like the well-known Hoka One One Bondi, use EVA.


A close-weave mesh is used for the upper unit of the Terrex Two Boa. This wraps the foot and keeps it in place. Though it has a taut interweave design, it still has tiny holes that permit air into the foot-chamber.

The Boa® Fit System on the bridge of this Adidas running shoe uses stretchy cables that snake through isolated fabric loops, as well as a twisting knob. Adjusting the tightness or looseness of the foot would merely involve turning the dial-like piece and feeling the modification taking place.
