The newly launched Saucony Endorphin Speed 4 introduces an upgraded upper that surpasses its predecessor, the 3. The noticeable improvements include a thinner and more breathable feel, making the running experience even more comfortable. A standout feature for me is the enhanced ventilation at the top of the toe box, thanks to strategically placed small holes that allow a refreshing influx of air. The gusseted tongue, now wider and longer than the v3, boasts small holes as well, ensuring it stays in place during runs. Despite the slightly scratchy texture of the collar and inner lining, the heel lockdown remains impressive.

The Endorphin Speed 4 maintains a true-to-size fit with a narrow toe box, eliminating the need to go up a half size, unlike its counterpart, the Endorphin Pro 4. For those who prefer a wider fit, a wide version is also available. The only downside I’ve encountered with the upper is that, when wet, the color tends to run, potentially staining the white tongue and laces. Overall, the improvements in breathability and comfort make the Saucony Endorphin Speed 4 a solid choice for runners seeking a reliable and upgraded experience.

Saucony has dialed up the speed game with the newly released Endorphin Speed 4 running shoes. To amp up the quickness, they’ve made two crucial changes to the midsole. Firstly, it’s now firmer, providing a solid and responsive feel with every step. Secondly, they’ve cranked up the aggression on the forefoot rocker, ensuring smoother transitions and making it a breeze to up your pace. In comparison to its earlier version, the Endorphin Speed 4’s midsole is approximately 10% firmer, resulting in enhanced stability. The widened base adds an extra layer of support, making your footstrikes feel firmly planted. So, whether you’re chasing a personal best or simply enjoying a brisk run, the Endorphin Speed 4 has your feet covered!

The Saucony Endorphin Speed 4 introduces a revamped outsole that elevates your running experience. Building on the success of the Endorphin Pro 4, the forefoot rubber now boasts a raised pattern, delivering a superior grip that excels in traction. I put them to the test on wet terrains and encountered no slip-ups, thanks to its effective traction. Keep in mind, on the lateral heel, the rubber stops a few millimeters shy of the edge, causing minimal scuffing for heel strikers. However, rest assured, this doesn’t hinder the overall ride quality – ensuring you enjoy a smooth and confident run.
