The Saucony Endorphin 2 is light

Everything about the Saucony Speed 3 gets a thumbs up from us, save for the heel counter. It's less padded, which is slightly abrasive to the heel. You can stock up on the bandaid or consider Saucony Grid Web 'Black Orange'.

However, if you're head over heels in love with the Extra Butter Unveils Its Saucony Collab Samples but want a comfier heel wrap, it's best to stick with the Saucony Endorphin Speed 2. It's also a great alternative for those with slim feet.

Durability

Outsole hardness

As a speed-oriented shoe, it is expected that the Endorphin Speed 3 cuts corners on the outsole's durability.

Not only do we see less rubber at the bottom, but we also found it to be softer than average with he help of a durometer.

If you don't mind sacrificing 0.6 oz of weight in return for a sturdier outsole, we can highly recommend the Saucony Jazz collection.

Cushioning

With the amount of cushioning that it packs, the zapatillas de running Saucony minimalistas talla 46.5 baratas menos de 60 is a mile eater. And a very good one too!

Even though our calliper shows an average amount of stack height (34.1 mm in the heel), it definitely feels like plenty on the run.

Important note: the brand advertised slightly different numbers. The shoe is supposed to have 36 mm for the heel stack height.

As for the forefoot stack, our calliper returned 26.7 mm which is over 2 mm thicker than average!

However, it is a little less than the officially stated 28 mm.

Drop

At 7.4 mm, we found the shoe's heel-to-toe drop to be close to the official specs (8 mm). This is a middle-of-the-pack drop that works great for both beginner and seasoned runners.

Measuring the shoe's insole, we found it to be slightly thinner than average at 3.6 mm. But this is still quite padded for a speed trainer - no need to be concerned with underfoot comfort.

Midsole softness

Note: a low durometer measurement equals a soft material, whereas a high measurement means it's firm.

The Endorphin Speed 3 also gets comfier than its predecessor. There is a gentle give in the shoe's midsole and it works better for easy days too!

Turning to our durometer, we found that the shoe's foam is in fact in the top 10% of the softest in our lab!

It was incredible to find out that the Endorphin Speed 3 remains soft even after 20 minutes in the freezer!

At room temperature, our durometer showed 13.8 HA and after the freezer, it only firmed up by 5%(!) becoming 14.5 HA.

Ride

This time around, the Endorphin Speed 3 comes back with more bounce and a snappier toe-off which makes picking up the pace so easy!

zapatillas de running Saucony minimalistas talla 46.5 baratas menos de 60 run trails

The shoe lives up to our high expectations left by the previous Speed 2.

And this is not just because it's a shoe that has speed written all over it. It's also because the nylon plate it has (responsible for the snappy toe-off) doesn't feel harsh. Compared to other plated running shoes, the Endorphin Speed 3 is more natural-feeling.

At the same time, the shoe hasn't lost its bounce either. So you can still push the pace and go as fast as you want.

What's more, in this iteration, the shoe's Speedroll rocker geometry is very noticeable. Each step feels as if the foot is carried forward. Love it!

Stability

Saucony Triumph 20 Men's

This Saucony shoe doesn't feel very stable and it's not supposed to. As a speed trainer, its primary task is to keep you on your toes as you smash that interval training or chase that new personal best.

There is not much stability to lean on when you decide to slow down.

Torsional rigidity

Another detractor from the shoe's stability is its high level of torsional flex.

Performing a manual test, we rated the Endorphin Speed 3 with only 2 out of 5 for torsional rigidity. That puts the shoe on the more flexible side of the spectrum.

Heel counter stiffness

Now we have Saucony pairing up with.

This is the ONLY complaint we have for the zapatillas de running Saucony minimalistas talla 46.5 baratas menos de 60. The shoe's heel is a tad bit uncomfortable and scratchy because it has minimal padding.

This is definitely due to the choice of materials because the heel counter itself is very soft, it scored 2/5 on our flexibility tests (5 being the stiffest). 

Their recommendation? Wearing thicker socks is a must. As well as carrying a couple of bandaids.

We also found that the Endorphin Speed 3 runs slightly narrow in its platform.

The widest part of the forefoot turns out to be 111.5 mm, 1.5 mm narrower than average. But the good news is that it's not so critical and the brand did its homework to improve the 3rd iteration.

The Speed 3 is proof that Saucony really listens to runners' feedback. In the past, the Endorphin Speed's weak point was its lack of heel stability.

But this model changes all this. Based on our calliper measurements, the shoe's base has been widened by 5 mm in the heel.

Flexibility

Stiffness

As our manual flexibility test shows, the Endorphin Speed 3 is on the flexible side. But let's see what the controlled lab measurement shows us.

In this test, we bend the shoe to a 90-degree angle and use a gauge to measure how much force it takes to do that.

Turns out, this Saucony shoe only needs 23.5N! This is 30% less than it takes a road shoe on average. This also proves that the nylon plate embedded into the shoe's sole is more forgiving than a carbon plate.

Grip / Traction

The outsole has plenty of traction and plenty of durability too! We felt safe at all times, even on wet asphalt passages. And during fast corners, the grip doesn't compromise.

Size and fit

Toebox width at the widest part

Even though the Speed 3 is only average in the widest part of the forefoot (98.5 mm), it feels roomier because of the stretchy nature of its fabric. The latter makes the shoe feel much more accommodating in the toebox.

We believe that Saucony absolutely nailed the fit of the Endorphin Speed 3! The upper does a really great job mimicking the natural shape of the foot.

The shoe's secure wrap is also complemented by its semi-gusseted tongue and padded laces. They work so well together; getting a solid lockdown won't be a Fille in the Speed 3.

Tongue padding

There is also a moderate amount of tongue padding - 3.9 mm, based on our calliper measurement. It is 2 mm thinner than the average but is just perfect for a speed shoe.

zapatillas de running Saucony minimalistas talla 46.5 baratas menos de 60 vs. 2

This version of the Endorphin Speed doesn't go through a lot of changes, which is why runners continue to rave about it. It has minor touch-ups, which make it an even better version: 

  • The wider toebox and thinner, stretchier upper for a more precise fit and a breathable running experience 
  • Saucony Shadow 6000 Navy Yellow 
  • A new plate for a snappier toe-off
  • Stripped-down heel padding to minimise the bulk as much as possible
