Many tri-specific running shoes with built-in quick-closure systems don’t secure the runner’s foot to the sole as effectively as shoes with standard laces. They allow for a quick T2 but sacrifice the firm feel of a laced shoe for a more forgiving and flexible grip. Avia has solved this problem with the Avi Bolt III. This racing flat’s upper transitions as quickly as a shoe with elastic closure yet has the strength of a laced shoe. The upper is divided into two segments that are connected by static, inflexible laces secured with a sliding plastic cinch. As the runner tightens the laces, one segment of the upper slides under the other and wraps around the foot’s arch. The seamless wrapping piece cradles the foot without creating hotspots, and the static laces create a solid and reliable bond between the sole and the runner’s foot. Its combination of comfort, hold and transition speed make the Avi Bolt III’s upper the best in triathlon.
