With a competitive-oriented design, the TR903 focuses on the speed of threading, foot stability and comfort without socks, while maintaining a high yield on the bike part.

Moisture design and management

Water and breathable resistant upper

The might associates synthetic microfibre leather resistant to water and fast drying mesh panels positioned strategically. This construction promotes aeration and accelerates the evacuation of moisture after the swimming phase.

Hollow carbon midsole

The hollow carbon sole, very rigid, effectively drains the water and allows the feet to dry faster. It also contributes to the stability of pedaling and direct transmission of power.

Fast adjustment and transitions

BOA® System LI2 System

The BOA® LI2 dial allows fast and precise micro-adjustments. It ensures a homogeneous maintenance of the foot, both during intense sprints and longer distances.

Quick Dry T1-Quick Strip

The wide T1-Quick band, associated with an extra-large opening, simplifies the insertion of the foot into the shoe and significantly accelerates the transitions.

Large heel loop

The oversized heel loop is easy to grasp, put on and quickly secure the shoe out of bike park.

Maintenance and stability

Heel stabilizer

The heel stabilizer maintains the foot in an optimal position when transitioning to the bike and during powerful accelerations.

Lining adapted to barefoot

The internal lining is designed to be used without socks. Its soft padding limits friction and improves comfort over the duration of the event.

Power transmission

Stiffness index

Stiffness index Shimano : 10, offering an excellent compromise between pedaling efficiency and tolerance, perfectly adapted to the triathlon.

Small sole height

The low sole height improves the stability of the foot and optimizes power transfer, strengthening the foot-pedal connection.
