The Best Road Running Shoes of 2020

Nike expands its NEXT% collection with a new model to complement the Alphafly: the Nike Air Zoom Tempo NEXT% Flyknit.

What immediately grabs the attention is its massive sole (46 mm stack under the heel!) with a curved shape that looks like an arch. Another important point is its nylon plate. It improves propulsion by ensuring a smooth transition while running. The big difference compared to a carbon plate (like the one on the Alphafly) is its firmness: carbon is lighter but firmer than nylon. Thus, the blade on the Tempo is softer, which makes it less noticeable.

In terms of running sensation, runners found the cushioning of the shoe very comfortable while being rather firm underfoot. This configuration makes the platform relatively stable despite the impressive stack height. As a result, the shoe is more stable than other models equipped with ZoomX foam. According to them, this is the work of the React foam under the heel. They also found the ride pleasant and responsive even at a slow pace, which is not always the case with propulsion plate running shoes as they are primarily intended for racing and fast speeds. Nike seems to position the Tempo as a fast and versatile trainer with its medium weight (252 g) and nylon blade, and the Alphafly as a competition shoe with its carbon plate and featherweight.

Moving on to the upper, Flyknit is quite breathable despite its somewhat "plastic" appearance. It is not very stretchy for a more precise foot lockdown without reducing comfort. The shoe remains spacious overall, especially in the toe area. However, some runners have found it too narrow in the midfoot, which may not be suitable for everyone.

Overall, the Nike Air Zoom Tempo NEXT% Flyknit is a very good, comfortable, and versatile trainer with high-stack yet firm cushioning and a nylon blade.

The third model of the very successful Endorphin collection is a tempo running shoe: the Speed. Complementing the Endorphin Shift (trainer) and Endorphin Pro (versatile with carbon plate), this shoe stands out for its snappy ride at fast paces. Its neon hues and fun design also make it a very appealing shoe. The Speed's midsole is one of the most notable features of this model. Made with PEBA-based PWRRUN PB cushioning, Saucony claims that this material offers an explosive energy return. This high-stack shoe (33 mm under the heel, 25 mm under the forefoot) also features a full-length, S-curved nylon plate, and SpeedRoll geometry to provide a smooth and comfortable transition from heel to toes. Testers unanimously enjoyed the ride, but with one caveat: you have to run fast as the shoe is a bit too harsh at slow paces. The Speed is noticeably much lighter than the Endorphin Shift, giving it a more weightless feel. Runners remarked that the upper of the Speed is particularly excellent, with FORMFIT technology that enhances comfort and breathability. Meanwhile, the outsole contributes to the propulsion of the shoe, engineered with durable rubber that grips terrain and stabilizes the foot. Those who tried the Speed commented on a few drawbacks of the design. The rear and plate of the shoe, though cushioned, proved a bit too firm for some runners. However, this rigidity lessened overtime. Runners also questioned the price point of the Speed, which is $40 less than its Pro counterpart but doesn't offer the same versatility and comfort. The Speed is a great tempo shoe, meaning that it works well for interval or tempo runs, but it is not a daily trainer. Runners searching for running shoes suitable for all workouts will prefer the Pro over the Shift. Overall, the Saucony Endorphin Pro is a very good running shoe with comfortable and responsive cushioning for fast running, even though its firmness may not be to the liking of everyone.
