But the forefoot area is rockered and slightly elevated, so the actual drop from the heel to the forefoot is lower than what you’ve concluded, even though the midsole thickness you’ve measured is correct. It’d be interesting to measure the midsole heights from the ground level.
I have one. Everybody is complaining that its narrow but i find that its perfect. I have a wider feet than normal and mach 6 fits like a glove. The length is perfect, the width is perfect. In terms of running characteristics, its fairly bouncy considering its just an updated EVA. Bouncy and light is how i will describe it. On the other hand, mach 6 is not great for walking, the midsole is quite hard but then its a running shoe not meant for walking around. For me though, still prefer the fuelcell midsole from NB, gift from heaven for feet
Love your site and this channel, has really helped with shopping shoes. But as a wide footer, could you please do measurements for the midfoot too on your site?
Something to consider is the rebel v4 doesn’t come in 2e in a lot of countries whilst the Mach 6 does and I would be guessing the Mach 6 2e would then be wider than the rebel v4.
Love your reviews! Any chance on reviewing one of Norda’s shoes any time soon? Seems to have a cult following / gaining popularity among the trail running scene. Also has some less common materials so would love to see how they perform on your tests.
the world athletics way of measuring is only good if there is no rocker and high stack... the only modern brand that this method will be meaningfull will be Vivobarefoot. 75% of the length of the shoe nowadays is far forward from the leveled area at which the shoe rests and the foot is affected by the drop.
Yeah, it's a question of technicality vs. substance. The official guideline seems to ignore rocker geometry, allowing manufacturers to innovate wildly with midsole shapes while remaining "legal." Personally, I'm just doing this for fun & health. I don't book flights & hotels to join races. I do want to know a shoe's heel drop because it can feel different. I appreciate RunRepeat for verifying the measurements, as they give us a number to compare to other shoes. But a number might not be enough to give the whole picture of the experience.
@@rogerx9298 While most of the measurements RR gives are awesome, I'd argue drop leaves much to be desired. Shoes are designed around a last, a generalized foot shape, and like feet that varies from one design to another. In particular the centerpoint for the heel and ball can be a bit different from one to another. Furthermore, tweaks to the shoe design beyond the last (ie. heel cup, how much space in the forefoot) will further alter how much space there is fore/aft of the foot after the last is placed in the shoe, which makes taking precise measurements based on the relative length of the shoe arbitrary. The WA is a spec to regulate race shoes, it shouldn't be taken as anything more than that. Isn't it just a tad odd that these cut in half measurements are often very off from spec? What is the incentive for manufacturers to dupe customers about something like drop?
@@brandall101 I agree the number isn't an accurate depiction. If they're going to measure 75% anyway, why not add measurements from 0% all the way to 100%? But then in addition to the stack thickness, the rocker and heel bevel elevates part of the shoe off the ground. Even the softness of the cushion varies at different parts of the shoe. In the end, I just want to know how it feels to run with the shoe. How different is it to land on the heel compared to midfoot or forefoot? A single number couldn't possibly describe the experience, and already I've seen it referenced in other videos without context. In all fairness RR did describe the experience as being different from the number. But the number is the one that gets referenced, not the description. I look at heel drop the way I look at shoe size. One shoe's Size 10 is not the same as another shoe's Size 10. It's the number the manufacturer chose for the shoe. Its not necessarily how I would experience it, but it is a number I can look at as an estimate.
@@rogerx9298 I'm going to go out on a limb and say that manufacturers are often quite accurate and above board about drop, but for reasons above, testers aren't going to be able to accurately verify that (aside from averaging a range, that may normalize things some). Stack height they may fib about a bit as there is incentive for marketability against easily verifiable weight. I've gone through a barefoot/zero-drop phase, a 4mm drop phase,, an 8mm drop phase, and have lately been mostly in 6mm shoes. I've owned a number of 10-12mm drop streetwear sneakers but have never consciously run in a shoe with that much drop. So I know what each level feels like, and rarely do I feel a shoe is off by 2+mm. I've put 200 miiles on the Mach 6 - this feels much closer to 5mm than 10mm. You do make a good point about loading the shoe esp. as that can impact perception, and other elements of midsole design that impact the experience in motion.
I have 200 miles on my pair with almost no wear there as a midfoot striker. It's fairly soft back there, but probably not the best choice for heel strikers.
Shouldn't heal drop be measured while the runner is wearing the shoe? I'd assume it will vary depending on runner weight while wearing. An unloaded shoe might measure specific drop but once you put on the shoe wouldn't there be a difference? Just curious. Thanks for the great content!
No. You don't measure while wearing the shoe. Everyone's weight is different. The only that maybe should be changed is whether or not they should stick to the World Athletics standard and having an additional drop measurement right that measures before the start of the rocker.
@@faocisco yes, you’re absolutely right and they also have different running gates that compress the shoe in different ways. It makes this stuff very complex and I commend this website for at least trying to come up with some type of standard. I just listened to a bunch of doctors talking about this stuff where once your bodyweight comes down in the shoe it could compress it to the point where it becomes a zero drop before it starts to rebound. I don’t want anybody to think that I’m digging on this website because they’re great but there’s also a lot of things to consider that are not discussed.

Love RunRepeat ❤❤
yep helps me decide which shoes to get.
Agree, they have always gone above and beyond in show reviews!
As others have commented, your measurement of heel drop is a bit hokey (sic). Look at how the cut in half shoe sits at 6:05 in the above
Thanks man !! This channel and site is seriously underrated.
that’s the first time I run in to your channel .. very nice and informative video dude 👍
Great review! Keep doing these in depth reviews as you guys are the exception in a real in depth review of running shoes
I always watch your review on your web before deciding buy a shoes.
Could you guys do the Hoka Cielo road? I’d love to see your measured stats for that.
This channel will become the mkbhd of running shoes

Omg, a review with facts! Thank you!

在台灣這邊，REBEL V4有2E，且比Mach 6 2E還寬。
Machines 6 wide is not the. Rebel V4 is really wide in the normal width.
Nice review
Love the vid 🔥

I actually felt that high drop with the Mach 6. Fortunately I have a shoe that felt a bit similar to it so I adapted to it faster.
Do the wide versions of the Mach 6 solve the small toe box issue?
Thank u from Germany
Can you guys add rebound testing?
We would love to, but we haven't found a good way to do it. Ideas?
@@RunRepeatcom dropping steel ball and see how high it bounces? I think it would be relatively good enough

its missing the outsole just where the heel strikers hit the road most.
