DELTA TRI OP Performance Review

I have been obsessed with running for 6 years, during which, I’ve tried many different running shoes. And among my running shoes, one of my favorite is the Descente . But it is quite strange that I can not remember the brand name clearly,  but I am rather impressed by the Descante logo. Maybe it is because of the special meaning behind it: it not only represents the brand, but also the spirit of pursuing excellence and bold innovation.

DELTA TRI OP is a high performance running shoe developed in collaboration with the Swiss National Triathlon Team. And since I am quite lucky to have gotten this running shoes, I hope this review can do some help for you.

The shoe box is light gray on the outside, which looks not so striking while the logo in the middle of the box is eye-catching and stylish.

There are mainly two colorways of the DELTA TRI OP, which are black and red while the one I got here is bright red  on the whole and has  a strong sense of visual impact. The shoe body is slender and narrow and without much fancy decoration on the outside, the shoe looks very simple but elegant at the same time.

The upper is made of P.W Upper engineering mesh with excellent air and water permeability which should be credited to the mesh holes inset which is quite visible with our naked eyes, and the vamp is also very thin and breathable.

Between the sole and vamp, a thermoplastic patch is used  to improve the durability of the shoe and prevent the toe from being too soft, which can result in sufficient support and protect the toe. And the reinforced crashproof toe which is slightly upwarped can offer the runner kind of thwart. Besides, the mesh holes on the vamp, to some extent, reduce the weight of the shoes and make it very comfortable to wear.

As for the midsole, it is equipped with a unique DELTA SYSTEM,a fabric based self-reinforcing KaRVO plastic laminates with high rigidity, which can not only keep the midsole ultra-light, but also stabilize the shoe body, increase flexibility and provide strong thrust. And the ring at the heel is designed here to help put on and take off shoes quickly. In the middle of the insole also lies a white Descente logo which is  iconic.

The shoe is also special in that DESCENTE makes use of the innovative sewing bonding technology, which makes it possible for runners to wear the shoes barefoot. And even in that case,  the wrapping is still very nice and comfortable.

The black rubber sole is made of graphene, which makes the sole durable and wear-resistant. Combined with special triangular groove design, the sole has a strong grip on the ground and can prevent slipping on wet grounds.

For the cushion, it can be easily felt. When I was warming up before exercising, I could obviously felt the soft cushion and the responsive feedback.


To sum up, the DELTA TRI OP aims at making up the slow of pace caused by fatigue. And the designer has integrates the excellent air and water permeability, the nice midsole, and durable soles into the shoe, making it  especially suitable for professional runners and runners with the pursuit of speed for daily training.

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.
