    If you are looking for an awesome lightweight racing flat with slightly higher volume and a partial TPU midsole, then I would definitely check the Endorphin Racer 2 out.

    With the Endorphin 2, I found that when I had a ideal fit from the ball of my foot back, the toe box was radically too small.

  • Starting with the upper updates of the second version of Saucony’s Endorphin Racer, a single layer of mesh was placed on this area of the shoe to entirely cover the foot. Staying true to the ultra-lightweight theme of the shoe, the material that Saucony used does not add to the weight, but provides the foot with enough breathability and protection. Minor revamps were made on the design of the upper and the construction of the lacing system.
  • Most of the updates on this shoe were concentrated on the midsole and outsole as Saucony attempts to improve this racing flat’s cushioning, responsiveness, traction, and durability.
  • The midsole SSL EVA on the forefoot was replaced with an EVERUN forefoot material to provide a more responsive type of cushioning that helps to evenly distribute the force felt by the runner upon ground impact. The rest of the midsole retains the SSL EVA material, but the switch allows the runners to experience an enhanced ride.
  • On the outsole, the XT-LITE material from the first version of the Endorphin Racer was updated with a PWRTRAC tacky rubber compound. This innovation aims to heighten the traction capability of this iteration and make it more adaptable to various terrain.

The Endorphin Racer 2 comes in standard shoe measurements. Runners will be able to choose from standard shoe lengths, as well as widths. The shape of the shoe is curved, following the natural lines of the underfoot. In addition, it’s important for runners to remember that the arch structure of the shoe is low, the stack height is minimal, and the offset is 0mm.

The Saucony Endorphin Racer 2 was meant to be a road shoe, but with its PWRTRAC outsole, it can tackle different terrains without the runner slipping or sliding. The PWRTRAC, which is also used in the Saucony Ride 10 road shoe, is a rubber compound with a tacky characteristic for better traction.

To enhance this outsole feature further, the tread pattern was designed with triangular protrusions and indentions in different sizes and going in different directions. This tread ensures that the grip of the shoe on most surfaces is secure.

In addition to the characteristics mentioned, the PWRTRAC is also highly resistant to abrasion and is a durable compound rubber. This means that the shoe may be able to last for a longer period of time even with continuous usage.

There are two parts to the midsole. On the forefoot is the EVERUN which concentrates on providing a responsive cushioning. To allow this functionality, Saucony placed this technology closer to the foot. It adapts to the runner’s needs through the combination of the molded SSL EVA on the heel. When the runner’s heel lands, the EVA absorbs the shock while the EVERUN reduces the pressure on the forefoot during take-off. The EVERUN midsole foam is also used in the Hurricane ISO 5.

Water drainage ports were also provided to reduce the shoe’s weight as well as aid in the ventilation dynamics of the shoe.

On the upper is a single mesh layer that covers the foot entirely. This material is lightweight and very breathable. Upon closer inspection, the material the upper is made of is somewhat see-through. That’s how thin it is. This doesn’t offer much in terms of protection, but the shoe was built for speed rather than every day or trail running.

To provide a lightweight lockdown to the midfoot, FlexFilm overlays were added. From the name, these overlays can move easily when the shoe bends, expands, or twists. The overlays are not rigid, but they still provide minimal snugness and security to the midfoot.
