  • The Asics Gel Tambora 4 trail running shoe is a lighter version and it has an improved upper construction that is more breathable and tougher. It is made from mesh material with synthetic leather, offering the combination of breathability, support, and durability at less the weight. The Hoka One One Speedgoat 3 is a shoe with a similar function.
  • The upper is constructed with California Slip Last that is added to provide stability, support, and comfort. It is stitched directly into the EVA board and it enhances the durability of the inner area. A Removable Sock liner that is molded to the shape of the foot is added not just for soft comfort, but also for a medical orthotic.
  • Another update of this version is the Rearfoot Gel cushioning added to its cushioning system. This cushioning enhancement provides the support and protection against impact and shock while keeps the shoe comfortable and bouncy.

The Tambora 4 has an outsole designed for trail running. The Trail Specific Outsole used in this shoe provides the traction and grip through the reversed lugs. This design has an aggressive pattern on treads, allowing the shoe to track mixed terrains and different outdoor surfaces.

The midsole of the Tambora 4 have minimal construction for neutral runners but are soft and comfortable enough with great protection against impact and for shock absorption because of the addition of the Rearfoot Gel Cushioning technology.
