DELTA TRI OP Performance Review

DELTA TRI OP was born on DISC OSAKA, it’s developed by Desant and Swiss national triathlon team. It’s designed for the 10km triathlon running. The Swiss national team will also wear DELTA TRI OP to participate in Tokyo Olympic games. DELTA TRI OP is dedicated to making up for the lost of step size due to fatigue.


DELTA TRI OP has red and black one. The colorway that I tested is red one. It’s very attractive under sunshine.

The shoe tree of DELTA TRI OP is a little narrow. It’s not so wide like some running shoes. If your foot is wide type, it needs to choose half size or one size bigger. My foot is not wide, so I choose the normal size.

The vamp only has the Descente logo, it doesn’t have other decorative element. The design is succinct.

The shoe head is upwarping.

It has pull-tab design on the shoe heel for putting on and taking off.

The shoe-pad is printed with white Descente logo.

The Excellent Air Permeability and Permeability Performance

To coordinate with the competitive request of bare feet, Descente designed the Loose Layer Fit structure that reduces the seams in the shoe and keep the insole flat. Meanwhile, Descente used the innovative sewing bonding technique, so that the shoes can fit the foot very well, and it’s very comfortable.

In addition, in order to cope with the wet and humid environment in the competition, the vamp uses P.W upper mesh fabric which has excellent air permeability and permeability performance. It has drain hole on the shoe-pad and sole, and suppress the pressure of vamp due to water absorption. This kind of design is unusual.

The hollow-out shoe lacing holes and cyclic annular design is favour of air permeability and conductive to the athlete to change the shoes fastly.


After swimming and cycling, it will lose a lot of energy, step length will be shorten, the DELTA TRI OP devotes to make up the step length loss caused by fatigue, Descente develop the DELTA SYSTEM which can maximize the running impact absorption system in the bottom, which carry high stiffness enhanced KaRVO plastic layer plate on the basis of the fabric. It keeps the light insole and also offer flexible resilience and excellent cushion to offer running driving force. It’s similar to NIKE NEXT% running shoes which insert the carbon plate on the insole. The Delta system is the core of DELTA TRI OP. It can reduce the pressure when running 10km.

Durable Outsole:

The black rubber of outsole adds the graphene components which improve the abrasive resistance. With the special triangle cutting groove design, the traction performance is great.

Running Test

After wearing DELTA TRI OP, the first feeling is light. The weight is really quite light.

Secondly, it’s soft and elastic.

Third, the air permeability is great. I tested it at noon of Summer, but it’s not stuffy after running.

The running result of 10km exceeds the expectation. It’s amazing.


DELTA TRI OP devotes to make up the loss of strides due to fatigue to satisfy the competition request of professional triathlon athletes. It has excellent air permeability and water permeability. The insole has great cushion performance. The outsole is durable and has high traction performance. It’s a pair of perfect running shoes. It’s suitable for professional runners for daily training and competition.
