Take note of the runners you see in your common route, and also you’ll discover that the overwhelming majority of them heel strike, that means they land on the heel of their foot earlier than rolling by way of to the toes.
That’s in stark distinction to the mid- to forefoot strike that you simply’ll see on elite runners, which consultants say is extra environment friendly however usually troublesome for extra informal runners to come back by.

Sure, you learn that proper—in contrast to most trainers, which function extra cushion within the heel than the toe, within the Muscle Runner, the forefoot sits on high of 27.5mm of cushioning whereas the heel has simply 17.5mm. This design is meant to make it practically unattainable to heel strike, and thereby to enhance runners’ type over time.
Unsurprisingly, the Muscle Runners haven’t launched with out their share of criticism—practically each point out of the shoe on social media comes with commenters predicting Achilles blowouts. I made a decision to strive them for myself, and to see what a podiatrist needed to say about their distinctive design.

The story behind the Muscle Runners
Though heel hanging is understood to be much less environment friendly than mid- or forefoot hanging, it doesn’t essentially need to be a nasty factor. The issue arises when heel hanging causes runners to overstride, or step out too far in entrance of their hips, which generally is a recipe for damage. That was the case with the Muscle Runner’s inventor, Shah Behnamian, who couldn’t eliminate nagging operating accidents till he realized to land on his forefoot. When he went to search for footwear made for forefoot hanging, he got here up brief (although, to be truthful, they do exist—Newton has made some over time) and determined to make them himself.
Behnamian calls the footwear “Muscle Runners” as a result of he says operating within the footwear is extra “muscle intensive” than what runners who heel-strike could also be used to. (For that very same cause, the footwear come packaged inside a foam curler, and Antepes encourages runners to foam roll earlier than operating within the footwear to heat up the calves, in addition to afterwards to assist them get well.)
The 10mm heel-to-toe acquire (that means there’s comparatively little cushion beneath the heel, and plenty beneath the forefoot) is maybe the shoe’s most uncommon design ingredient (Behnamian got here up with it by experimenting with shaving down the heel on different trainers), however the Muscle Runner has another modern options, too.
There’s what Antepes calls the HeelX know-how: With a view to scale back contact on the Achilles tendon, the shoe’s higher sits about 5mm decrease than traditional on the heel, which is as a substitute locked into place with “extensions” on both aspect of the Achilles (that appear to be wings coming off the again of the shoe). That heel grip is particularly vital when forefoot hanging, when the heel is extra more likely to slip out.
The Muscle Runner additionally contains a carbon plate, which Behnamian says is extra versatile than the carbon plates in most different trainers, and is meant much less so as to add propulsion and extra to assist the toes and distribute weight to the ball of the foot. It additionally has a dual-layer TBE foam, with a softer foam immediately beneath the forefoot and a stiffer backside layer for floor contact to assist in stability when touchdown on the forefoot.
Behnamian admits that the shoe is “fairly aggressive,” and isn’t supposed to switch your day by day coach. The Muscle Runner isn’t designed to go additional than six miles, and ought to be used solely as an occasional coaching device. “This shoe is like taking your ft to the fitness center,” he says, including that except you’re already a robust forefoot striker, soreness is inevitable. He recommends beginning by operating simply half a mile within the footwear and dealing as much as barely longer distances.
Although his target market is highschool and collegiate athletes, Behnamian says he believes the shoe will help even informal runners who’re heel strikers develop a extra environment friendly operating type. And he provides {that a} extra accessible mannequin of the shoe could also be in Antepes’ future.
What a podiatrist has to say
American Podiatric Medical Affiliation spokesperson Mark Mendeszoon, DPM, a podiatrist who owns two operating shoe shops in Ohio and Pennsylvania, emphasizes that this shoe won’t be for everybody, and that it’s extraordinarily troublesome to alter your pure operating type. (He says that when he ran in Newton’s model of a forefoot-striking shoe, he developed Achilles tendonitis.) Although he’s skeptical that the shoe alone can change a runner’s type, he says it does have potential for runners who already forefoot strike. He additionally provides that the technical parts “appear to be top-notch.”
What the Muscle Runners really feel like on the run
After a handful of runs within the Muscle Runner, I’m glad to say that my Achilles are nonetheless intact. I did comply with Behnamian’s recommendation and proceeded with warning, particularly as somebody who positively heel strikes once I’m not enthusiastic about it. I haven’t run greater than three miles at a time within the footwear, and have given myself a number of days in between taking them out.
My first problem within the Muscle Runners was getting them on: The merino wool and tencel uppers don’t have a lot give (Behnamian says you technically don’t even want the laces—that’s how safe the higher is), and the heel wings are a bit tough to navigate.
I discovered that even strolling within the footwear takes some getting used to, and as soon as I began operating, I felt hyper-aware of how I used to be touchdown, and uncertain if I used to be doing it proper. (Ought to I keep away from letting my heels contact the bottom in any respect, or permit my foot to roll by way of to the heel? Can I land on my midfoot or does it need to be on the ball of the foot?) It took till about my third run within the footwear for me to have the ability to simply run with out enthusiastic about it, and I settled into some kind of forefoot/midfoot strike.
Although I felt like I used to be operating pretty uptempo (and my legs had been tiring accordingly), my watch tells me that my runs within the Muscle Runners had been amongst my slowest ever. That wasn’t totally surprising—in any case, the Antepes web site considerably hilariously advertises that operating within the footwear will “improve your coronary heart fee.”
After my first few runs within the footwear, I did discover some muscle and Achilles soreness, however nothing too out of the atypical. One place I did have ache: The backs of my ankles, the place I developed blisters from my heels barely slipping round.
Will I be logging extra miles within the Muscle Runners? In all probability not too usually, however I might see myself taking them out for a brief run often on days once I need to concentrate on my type—and might afford to be a little bit sore the subsequent day.
