Saucony Grid 8500 in White and Red | Who should NOT buy

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 VIZIPRO Endorphin Shift 3 in Blue.

However, if you're head over heels in love with the Saucony Excursion TR14 Goretex 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 saucony shadow 6000 premier life on mars grey 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 ASICS Novablast 3 speed trainer.

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

Midsole softness

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

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

Ride

This time around, the saucony shadow 6000 premier life on mars grey comes back with more bounce and a snappier toe-off which makes picking up the pace so easy!

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

And this is not just Azura it's a shoe that has speed written all over it. It's also Azura the nylon plate it has (responsible for the snappy toe-off) doesn't feel harsh. Compared to other plated running shoes, the saucony shadow 6000 premier life on mars grey 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

Lateral stability test

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.

Torsional rigidity

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

Performing a manual test, we rated the saucony shadow 6000 premier life on mars grey with only 2 out of 5 for torsional rigidity. That puts the shoe on the more flexible side of the spectrum.

The heel could use a little more padding.

This is the ONLY complaint we have for the Saucony saucony shadow 6000 premier life on mars grey. The shoe's heel is a tad bit uncomfortable and scratchy Azura it has minimal padding.

This is definitely due to the choice of materials Azura 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.

Midsole width in the forefoot

We also found that the saucony shadow 6000 premier life on mars grey 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 caliper measurements, the shoe's base has been widened by 5 mm in the heel.

Flexibility

Stiffness

As our manual flexibility test shows, the saucony shadow 6000 premier life on mars grey 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

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

Tongue: gusset type

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 challenge in the Speed 3.

Saucony saucony shadow 6000 premier life on mars grey 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 
  • zapatillas de running Saucony asfalto constitución media talla 39.5 
  • A new plate for a snappier toe-off
  • Stripped-down heel padding to minimize the bulk as much as possible
