pair for easy runs, another for intervals and something special for race day. Building a running shoe collection can become an expensive hobby before you have even paid an entry fee.
For runners hoping to keep things simpler, a shoe that can handle a hard training session and a race has obvious appeal.
That is the question surrounding the Saucony Endorphin Speed 6, which has a US launch date of Thursday October 15th. With updated cushioning and a revised plate, it gives runners another option to consider for the quicker miles on their calendar.
What Has Changed?
The Speed 6 introduces PWRRUN PBX foam and a reshaped nylon plate. Saucony describes the new foam as a lightweight, responsive PEBA material and positions the shoe for tempo runs, speed sessions and track workouts.
The Speed 5 used PWRRUN PB cushioning and a winged nylon plate. Its listed sole heights were 36mm at the heel and 28mm at the forefoot. The Speed 6 moves to 38mm and 30mm, adding 2mm at both ends while keeping an 8mm drop.
Those changes give existing Speed owners something more substantial to consider than a fresh colour scheme. However, extra cushioning and a different foam do not automatically make a shoe better for every runner. How the updated design feels underfoot will matter more than the specification sheet.
Where Does It Fit?
Saucony puts the Speed 6 in its training and racing category. Within the wider Endorphin range, the Pro 5 and Elite 3 use carbon plates, while the Speed retains nylon.
That gives this preview a practical focus: a runner looking for something to wear at the club session on Tuesday and a local race on Sunday.
Buying one pair for those jobs could be appealing, particularly if a dedicated racing shoe would spend most of the year in its box. Familiarity matters too. There is something reassuring about arriving at a start line in footwear you already know from training.
Still, a shoe suited to faster efforts is not automatically the right choice for every easy run. Readers looking for a single pair to cover their entire week should keep that distinction in mind.
Could You Race in It?
The intended role makes racing a reasonable use to consider. The more useful question is how well it suits the individual runner and the distance they have entered.
For a future review, we would want to know how secure the fit feels when the pace increases, how the shoe handles corners and wet roads, and how comfortable it remains over longer efforts.
A lively first few minutes would only answer part of that. A shoe being considered for both training and racing also needs to earn its keep across repeated outings.
We have not tested the Speed 6. This preview covers the published design and intended use, rather than offering a verdict on its ride or durability.
Price and Availability
Saucony lists October 15th for the US launch, with Running Warehouse advertising a price of $179.95.
At the time of writing, we could not verify an Irish or UK retail price or local order date. Readers should check regional availability before treating the US launch as confirmation that it can be bought here.
Is It One to Consider?
For someone happy with their Speed 5, a new version alone is no reason to rush out and buy again. The sensible comparison will be the price, fit and feel of each model.
For runners shopping for a pair to cover faster sessions and occasional racing, the Speed 6 has a clear purpose. The appeal is straightforward: one familiar shoe doing more than one job.
Now it needs to prove how well it does them.
