Saucony Endorphin Pro 5 Review: A Race Shoe With Its Magic Back

Introduction

Saucony’s Endorphin Pro line has long been a fixture in the carbon-plated racing scene, and the Endorphin Pro 5 arrives with some meaningful updates. After the Pro 4 felt, to many runners, more like a performance trainer than a true race day weapon, the Pro 5 sets out to reclaim some of that racing pedigree. Our first run covered just under 8 miles, mixing steady miles with faster intervals, and the early signs are promising: this is a shoe that feels lighter, nimbler, and noticeably more exciting at speed.

That said, it comes at a price, literally. In the UK the shoe retails for £249.99, a £20 increase over the previous version, and that makes the value question harder to ignore.

Who This Product Is For

The Endorphin Pro 5 is a performance-driven carbon-plated running shoe designed for structured interval sessions throughout training and for lacing up on race day. If you want a shoe that comes alive at quicker tempos and could plausibly carry you through a marathon, this sits squarely in that category.

Main Strengths

The headline change is weight. The Pro 5 is 6 g lighter than the Pro 4, with our pair in a UK 9.5 coming in at a decent 236 g. The stack height measures 39.5 mm at the heel and 31.5 mm under the forefoot, giving an 8 mm heel offset.

The midsole is a two-layer construction: a soft, plush layer of PWRRUN HG foam close to the foot, with PWRRUN PB foam underneath for comfort and high energy return. Sandwiched between the two is Saucony’s new slotted carbon plate, designed for a smoother, springier, quicker ride. Saucony’s Speed Roll rocker geometry rounds out the package, making the transition through to toe-off feel efficient and effortless.

On the run, this combination was where the shoe truly shone. At around 6:00 to 6:30 minute miling, the Pro 5 felt dynamic with every stride, with the new carbon plate delivering a good level of propulsion and the foam setup returning energy generously. Compared directly to the Pro 4, the 5s feel more nimble and responsive straight out of the box, and they feel more like a genuine race shoe.

The upper is a lightweight, highly engineered breathable mesh covered in small perforations for airflow, now with a smoother internal liner for comfort over longer distances. The knitted tongue is attached internally for a foot-hugging, bootie-like fit. Fit is true to size in true Saucony style, with snug midfoot lockdown and a secure heel hold. The midfoot void in the outsole, a potential stone trap on paper, picked up not a single stone across the test run.

Things to Consider Before Buying

The biggest consideration is the price. At £249.99, the Pro 5 costs £20 more than its predecessor, and that premium looks steep when some strong carbon-plated shoes from China cost far less. The Anta C202 7, for example, impressed on feel and performance and can be picked up in the UK for around £130, roughly half the price. Whether the Pro 5 is worth £120 more than that is a genuinely open question.

There is also an odd design detail: Saucony has placed the sizing label in the middle of the heel cup, made from a shiny material. In practice this caused no irritation or heel slippage during the test run, but the placement seems strange, and a side-of-ankle position would arguably have made more sense. The ankle collar and heel cup padding are also fairly stripped back, which is a reasonable trade-off for lightweight performance but worth knowing upfront.

One more note on fit: the Pro 5 is not a wide-fitting shoe, but it is not narrow either, especially considering it is a carbon-plated race shoe. The review perspective used a mid to narrow foot shape, and the fit worked very well.

Buying Advice

For runners who race or hit fast interval sessions regularly, the Endorphin Pro 5 delivers where it matters: a comfortable, breathable upper, an 8 mm offset, and a fast, efficient midsole setup with genuine propulsion at speed. It has the attributes of a quality marathon shoe, and after a first run of 7.82 miles that were enjoyable throughout, it feels like Saucony has brought back some of the magic of earlier Endorphin Pros.

If you are price-sensitive, it is worth comparing against alternatives before committing. The Pro 5 is the more exciting, more race-ready shoe, but at roughly double the price of some very capable competitors, the value case is not automatic.

Conclusion

The Saucony Endorphin Pro 5 is a successful update: lighter than before, more responsive at quicker tempos, and genuinely exciting to run in at speed. It restores the racing feel that the Pro 4 lacked, and it looks the part in the black and citron colorway. The only real sticking point is the £250 price, which puts it in a tough spot against cheaper rivals. If budget is not a concern and you want a proper race day shoe, it is an easy recommendation; if value drives your decision, weigh your options carefully.
