Saucony Endorphin Shift 3 Initial Review: Shifting to a Lighter, Softer, Mellow Giant!

Article by Sam Winebaum

Saucony Endorphin Shift 3 ($150)


Introduction

The Endorphin Shift joined the uptempo Speed and racer Pro as the long run, max cushioned, up tempo trainer in what in 2020 was the then all new Endorphin line. And a super successful line it has been for Saucony with focused offerings for different run types all popular and pleasing in their own right. The Shift got an upper update for its v2 as did the other models. 


With V3 of all three we see quite dramatic evolutions with lighter weights for each.  The Speed 3 (RTR Review) gets a somewhat broader and softer platform which is also more stable leaning it a bit more towards daily training but staying the same in weight, while the Pro (RTR Review) jumps up to the max stack height "legally" by World Athletics allowable for racing while reducing its weight with a softer ride that broadens its use to more runners and more run uses.   


So what did Saucony have in store for the Shift 3? Well for sure in the trend of the other two lighter weight, 0.9 oz /  26g  lighter than v2 with a slightly higher stack height to a near max “legal” 39mm at the heel with the 4mm drop remaining unchanged. Most of the credit I think goes to Saucony's new lighter softer PWRRUN foam.

A new midsole geometry with a more symmetrical rear plastic clip with the heel very deeply embedded in the midsole, a new upper and a thick 7mm PWRRUN+ sockliner join the changes. 


I have gone on 2 runs to date including an initial 6 mile run with a short A/B run with v1 on the other foot and share initial impressions (and will update after more runs) ahead of our multi tester review. Note that I ran v1 but not v2 of the Shift. 

Pros:

Very light yet substantial on foot

Softer, more forgiving midsole foam and some flex unlike earlier versions

More mellow softer and more flexible ride may broaden appeal

Still stable and plateless

More secure upper, especially at the rear. Very comfortable too.

With deep rear medial clip removed, stability is moved forward through the side walls geometry

with ride more fore to mid foot focused. (also may be a Con for some)

Still $150.


Cons:

Less uptempo in feel, more mellow and easy going almost too much so for me

Not as friendly to slower paces and heel striking as prior versions. Lower feeling heel and softer

Less of a long roll sensation due to the softer foam, more medial support, less outsole coverage, and as before 4mm drop

First Impressions, Fit and Upper



My pair is striking in its all white with subtle gold accents. The mesh is light and airy and quite unstructured, reminding more of a slightly thicker version of the Endorphin Pro v1 upper than the Shift v1’s upper.


The fit is true to size with great heel hold from the new clip and the lightly and adequately padded collars with the inner collar linings having considerable texture and grip. Side by side with v1 the rear hold is clearly improved if less plush. I did not test v2.

The midfoot is held by a combination of a soft stretch gusset tongue and bands of quite thick but very pliable overlays running from the middle of the mid foot to the rear.

The tongue and lace up is particularly well executed with the same stretch mesh as the gusset lined over the lace up inside with another layer of smoother mesh with some sock grip and then on the outside a triangular logo which has some depth (to protect from lace bite) and bridges the width of the lace up. 

Lace up is very easy and very smooth through the eyelets and fuss free.

The toe box is unstructured and relatively broad. There are well placed overlays over the top of the top bumper with a bit of stiffening below that around the sides.  

The sockliner made of PWRRUN + TPU is about 7mm thick, most are 4-5mm thick, and not light at 31g. For example, the Endorphin Shift v1 and Endorphin Speed 3 EVA type sock liners weigh 16-18g. This ultra thick sockliner for sure contributes to the softer more plush vibe of the shoe compared to earlier versions. Never mind the white and gold launch color!


If you have a higher volume foot you can easily swap out for a thinner one in your collection. I tried the original and a thinner one and noticed minor differences in fit with the thin one providing more volume. I wore thicker Darn Tough socks and suspect with thinner socks I would prefer the higher volume supplied sockliner at my true to size medium to narrower feet.


The fit is clearly true to size for me with plenty of toe box room for splay. I only note a touch of top pressure from big toe side front overlays. The fit is generally more precise especially at the rear than my v1 sample which was a half size up from my normal.


Midsole

We get 1-2mm more stack height of Saucony’s new lighter, softer, and more resilient PWRRUN to come in at a maximal 39mm heel / 35 mm forefoot. While not as light as PEBA type foams, this flavor of EVA/TPU blend is darn light. For reference the Hoka Bondi 8 (RTR Review) with the same stack height and somewhat broader platform comes in 1.5 ounces heavier and that is for sure felt on the run as I have been testing the Bondi 8 recently as well.


The feel is softer than the earlier versions to pressing and on the run. There is truly a bottomless cushion here now, a bit more pleasant feeling than before and a touch less decisive and responsive in return speaking to the more mellow focus on the Shift 3.

There is no plate in the mix as in the Speed and Pro or competitors such as SC Trainer from New Balance (RTR Review).

To stabilize all that foam Saucony uses a symmetrical rear classic clip with the heel sitting very far down into the midsole around the clip.

This is instead of the big wrap around TPU heel counter used in v1 and v2 which had dipped yet lower to the medial side with the foot sitting not as deeply if much at all in the midsole. 

We are still very stable but the heel now feels lower I think due to the softer foam, a touch less support from the non removed deep medial heel clip and changes further forward. 

Saucony compensates for this through a fairly deep if narrow rear torsional groove to help the foot move to transition, but for heel strikers I think it could be deeper and more pronounced, along the lines of the SC Trainer. And removing foam there would reduce weight yet more!

While v1 and v2 pretty much ended the stability elements near the heel with an extension through its wrap up outsole. v3 through its higher vertical midsole side walls feels like the support medially is moved forward. 


While the shoe after 2 runs has developed some flex with the SpeedRoll less noticed than when I first tried them on.


Outsole

The outsole is very similar to v1 and v2 in overall design but we do see changes.

What doesn’t change is that the rubber is firm and should be long lasting.

The medial midfoot rubber is narrower and no longer wraps up the side walls. The front rubber keeps the raised outside lugs but goes to a single central strip which interestingly is lower than the white exposed foam around it. I imagine they will become level with some wear. I think both of these changes contribute to giving the Shift some flex and also removing some of its snap and pop rocker effect off the forefoot. More pleasant but I preferred the longer stiffer roll of the prior.


While stiff out of the box the shoe now has some flex and more so that my v1 already after one run with considerably more miles on it.


Ride and Initial Thoughts

I did a short run with v1 on one foot and v3 on the other then changed to v3 on both feet for 6 miles at an ending pace of 9:49 per mile, so on the slow end of what the shoe is designed for and my training paces but it was hot! I took them out the next day for another short run to confirm my thoughts.


Side by side the v3 clearly had a more secure rear hold than v1. 


V1’s ride was somewhat firmer and less bouncy, more snappy and responsive. V3’s ride was softer and had more rebound and flex. 


I found v1’s roll to toe off longer passing midfoot a bit easier . v3 felt lower at the heel and seemed to favor (the softer foam and the more aggressive forward medial support) a more forward strike, reminding me a bit of the New Balance More v3 in that respect. I tend to heel strike at slower paces and low drop softer shoes usually work better for me at faster paces than I went today. I think more copious rubber at the heel and forefoot would balance out the softness of the new foam and give the Shift back some pop.


The Shift 3 is following the trend of the Speed 3 and Pro 3 as it mellows its ride a bit with a softer, easier flexing platform. While I clearly, clearly appreciate what Saucony has done with the Endorphin Pro 3, one of my top any distance race choices of the 2022 so far and with the broader softer more easy flexing Speed 3, one of my top faster daily training picks with Shift 3 I will need more runs to determine its range and utility. 


So much stack, no plate, softer foam, 4mm drop, a fairly minimal outsole is a tricky combination to pull off. So far I am feeling the Shift 3 may be a bit too much of a “friendly” giant and for my tendency to heel strike. This wasn't the case with v1with its firmer ride and more structured outsole.  It felt a bit plodding and over soft but for sure light on foot. Next run will be more uptempo and I will update here ahead of our full multi tester review which will also include many comparisons.

I would love to hear if the new outsole grips a bit better on gravel and dirt road than the V1. I had some slight sliding back on toe off in the first version when accelerating, doing strides etc. Thank you and I cannot wait for the full review!

Mike said...

Could you please do a comparison against the Topo Specter.

Would be nice to hear how this version compares to Nike ZoomX Invincible Run 1/2.

Been looking forward to this review. My Shift v1 having completed nearly 900k - they have worn surprisingly well, I still run in them and feel good the following day. My replacement choices are the Tempus, Hoka Bondi 8 (I've run the 5 and 7) and Hoka Mach 5. Not a fan of the all white though.

So glad to see the comparisons to the Glideride 3 and Novablast! I'm interested specifically in the stability comparisons and toe-off roll comparisons. Thanks!

Chuck said...

$10 price increase from versions 1 & 2.

From this initial review it sounds somewhat similar to the On Cloudmonster. Could be a worthwhile comparison…

Sander said...

Would love a comparison with the Triumph!

Would be great to be compared to Skechers MaxRoad, NB 1080, as well as Hoka's daily trainers (Rincon particularly). Thanks!
