Who should buy the saucony Jazz Ignite Tri Suit

If you're looking for any of the following, then we highly suggest not skipping on the saucony Jazz Ignite Tri Suit: 

• a trail running shoe with maximum protection and minimal weight
• an off-road racer that's grippy on wet, dry, and muddy terrains 
• a shoe that can go fast and go the distance

Who should NOT buy it

The heel fit of the Endorphin Edge is rather sloppy. If you crave a dialled-in rearfoot fit, chances are you'll love the saucony Jazz guide iso 2 chaussures running RSCSA better.

Because it's downright awesome! The shoe's engineered mesh walks a fine line between ventilation and protection.

Using a smoke-pumping machine, we have visualised the shoe's ventilation capacity. Judging by the amount and speed of smoke, we gave the shoe 3 out of 5, where 5 is the most breathable. It is considered average for trail running shoes.

Minimal weight for maximum cushion

The saucony Jazz Ignite Tri Suit packs a tremendous amount of foam. And this fact made us speechless when we found out that the shoe only weighs 9.5 oz (270g) in US men's 9!

This is a whole ounce lighter than trail shoes on average but with a few millimetres more cushioning! Hard to believe, really.

Nothing can top the Edge's protection and comfort

Measuring the shoe's foam softness with a durometer also revealed that it is a good 40% softer than running shoes on average!

Good news for those who run in chilly weather - the foam doesn't get much firmer!

After spending 20 minutes in the freezer, the cushioning of the Endorphin Edge only got 14% firmer. For reference, most foams get around 26% stiffer on average.

The Endorphin Edge is a generously cushioned trail shoe. Measuring its stack height with a pair of callipers, we found that it is 33.4 mm in the heel and 26.3 mm in the forefoot. Compared to running shoes on average, it is 0.6 mm thicker in the heel and 1.9 mm more in the forefoot.

Ready to race...and win!

The combination of the high energy return given by the midsole, the snappy carbon plate, and the smooth and rockered ride felt mind-blowing and... even a little scary. That's because it takes willpower to slow down in this shoe! 

We believe that the shoe's explosive ride justifies the shoe's hefty £200 price tag. 

You better not slow down

It's clear that the Endorphin Edge is made for speed. Our attempts to run at a slow pace resulted in feeling highly unstable and even wobbly.

The stiffness of the carbon plate is one of the key features that help to keep runners on their toes in the Endorphin Edge. Measuring the shoe's stabil to bending, we found that it is 38% stiffer than running shoes on average.

This saucony Jazz shoe proved to be a stiff one in our manual assessment too. On a 1-5 scale where 5 is the stiffest, we ranked the shoe as 5 on longitudinal flexibility and 4 on torsional one.

Grip is king in the Endorphin Edge

Whether you're running on rocky terrain, wet trails, puddles, creek crossings, or even mud, you can manoeuvre the saucony Jazz Ignite Tri Suit with utmost confidence. And on the road? We found that it works on the pavement just fine!

We measured the shoe's lugs at 3.4 mm. This is the standard lug depth for trail running shoes.

Endorphin Edge keeps you steady

We felt quite stable when cornering in this saucony Jazz shoe. It has a solid amount of lateral support as well as a wide enough base to prevent the foot from rolling over.

Measuring the widest part of the shoe's sole with a calliper, we found that it is 112.6 mm in the forefoot and 88.2 mm in the heel. This is right at the average of trail running shoes.

Fit: Takes the distance into account

Meaning to say it has a generous fit that bears foot swelling in mind.

The toebox has plenty of wiggle room. It even welcomes wide feet!

In case you struggle with heel slippage, the shoe comes with an extra pair of eyelets to tie a runner's knot.
