Most reviews of the Saucony Endorphin Pro 4 will tell you it is a worthy competitor to the Nike Alphafly and Adidas Pro Evo. The honest answer is that the entire "who beats whom" framing of carbon-plate reviews is a category mistake. The right question is not which super-shoe is fastest. It is which super-shoe fits the runner you actually are, and whether the Saucony deserves a place in the conversation at all. I argue it does.
Why the Endorphin Pro 4 is the under-discussed shoe of the carbon era
Walk into any Mumbai or Delhi running group on race morning and the carbon-shoe distribution skews heavily Nike. There is a reason — Nike pioneered the category, ran a coherent decade-long brand campaign, and convinced amateurs that the Vaporfly was the shoe Eliud Kipchoge wore. Most of those amateurs cannot run a sub-three marathon. The shoe Kipchoge wore is not the shoe they need.
The Saucony Endorphin Pro 4 deserves a longer look. The verified specs: 213g weight, 39.5mm heel stack, 31.5mm forefoot stack, 8mm drop, PWRRUN PB foam, full-length carbon plate. Indian retail at ₹21,999. The intended use is marathon race day. On paper, this is exactly the carbon shoe most Indian recreational marathoners should be considering, and yet it does not get the column inches the Nike line does. That is the central thesis of this piece.
The 8mm drop is doing more work than you think
Carbon shoes with high drop have an under-appreciated advantage: they are kinder to runners who heel-strike or mid-foot strike, which is most amateur runners. The 8mm drop of the Endorphin Pro 4 sits in a position the literature broadly considers neutral-friendly. A 4mm-drop carbon shoe — like the Nike Alphafly 4 — assumes a forefoot bias that many Indian recreational runners simply do not have. If you have been running in 8-10mm-drop daily trainers for years, the Saucony's geometry is a shorter cognitive leap on race day.
How the Endorphin Pro 4 compares within its own brand
Saucony's stack is layered. The Endorphin Speed line uses a nylon plate. The Endorphin Pro line uses a carbon plate. The Pro 4 is the current top of the racing tree. The differences between Speed and Pro are not trivial — the carbon plate is stiffer, returns energy differently, and shifts the loading pattern in the calf and Achilles. If you have only used the Speed previously, do not assume the Pro 4 is a linear upgrade. It is a different tool.
Where I would pick the Endorphin Pro 4 over alternatives
I would choose the Endorphin Pro 4 over a Nike Alphafly 4 for any runner who:
- Heel-strikes or mid-foot strikes naturally.
- Has been training in 8-10mm drop shoes consistently.
- Is racing a marathon at a 3:30+ pace.
- Wants a shoe that feels stable through fatigue in the final 10 kilometres.
The Alphafly is a brilliant shoe for elite-pace forefoot strikers. Most readers of this review are not that runner. The honest answer is that the Alphafly often sells to people whose foot strike and pace would be better served by a higher-drop, slightly heavier alternative.

The case against the Endorphin Pro 4
I will not pretend this shoe is universally correct. Three cases where I would actively steer a runner elsewhere:
You are a strong forefoot striker chasing a sub-3 marathon
The Endorphin Pro 4's 8mm drop is not the most efficient platform for a forefoot striker. A lower-drop carbon shoe will likely return better economy. The Nike Alphafly 4 or other low-drop carbon shoes in the super-shoe comparison may be a better technical fit.
Your race goal is a 5K or 10K
The Endorphin Pro 4 is engineered for marathon distance. The cushioning is calibrated for the back half of a 42-kilometre race. For shorter, faster events, lighter carbon-plate flats from any brand will likely feel more responsive at 3:30-3:50/km paces.
You are looking for a daily trainer
This is not a shoe for easy miles. The PWRRUN PB foam is reactive but unforgiving outside of race-pace efforts. Daily-trainer duty kills the foam's lifespan and offers no economic benefit at Z2 paces. If you want a Saucony daily trainer, look elsewhere in the line.
The Indian context that no global review will write
Indian marathon racing happens in conditions Western reviewers do not consider. Mumbai Marathon's January 6am temperatures sit in the 18-22°C range. Delhi's late-October races push into the high-20s. Bengaluru's TCS World 10K is humid. Surfaces vary from new tarmac to broken concrete. Carbon shoes are designed for the abstract "marathon" — well-paved European autumn courses. The Indian application is harsher.
What this means for the Endorphin Pro 4 specifically
The 213g weight is in the lighter half of current carbon shoes, which is an advantage when you are sweating through eight per cent humidity. The 39.5mm heel stack provides cushioning that the back half of an Indian marathon — when fatigue meets uneven tarmac — will demand. The PWRRUN PB foam holds up reasonably in heat. The combination is more pragmatic than the Alphafly's max-stack racing geometry for runners who are not chasing sub-elite times.
Buying it correctly in India
Saucony's Indian retail footprint is smaller than Nike or Adidas. The Endorphin Pro 4 may not be on every metro shelf. The protocol:
- Check the official Saucony India online channel for current size availability.
- If you have not raced in a recent Saucony Endorphin model, do not buy online without trying on.
- If you have used the Endorphin Speed series, sizing typically carries over.
- Validate fit on a flat surface in the store — carbon shoes feel different than store-display foam might suggest.

The verdict — picking the right fight
The Saucony Endorphin Pro 4 is not the most marketed carbon shoe in India. It is, for a large segment of Indian marathon runners, the most appropriate. The 8mm drop, 213g weight, 39.5mm cushioning, and PWRRUN PB foam combination is calibrated for the runner who has trained in conventional daily trainers and is now ready to express that fitness on race day.
If you have spent six months telling yourself you need the Alphafly because it is what the elites wear, this is the moment to pick a different fight. Choose the shoe that matches your foot strike, your cadence, your race pace, and your training base. For most amateur Indian marathoners, the Saucony is the more honest tool. The marketing budget belongs to Nike. The shoe that may actually fit you sits one shelf over.
