As a former track and field athlete, I’ve tried countless pairs of running shoes from every brand on the planet. Though I’m retired now, I still love to run and I’m always on the lookout for the next best thing to level up my performance.
Recently, I've been intrigued by barefoot shoes. They're designed to let your feet move naturally, which helps strengthen the muscles in your feet, ankles, and lower legs. These shoes have a wide toe box that gives your toes the room to wiggle and flex, which boosts strength and helps avoid injuries. Plus, their zero-drop design means your heel and forefoot are at the same level, encouraging a more natural stride that's easier on your joints and better for your posture.
The Flux Adapt Runner is one such shoe that’s designed to mimic the natural feel of barefoot running. I wanted to test it out against the much-hyped Hoka Clifton 9, the influencer-fave that’s known for its plush cushioned support.
So, here’s how these two running shoes with drastically different approaches compare:
If You Prioritize Comfort For All-Day Wear … Flux
Both the Adapt Runner and Clifton 9 are comfortable for a quick run but after walking around in each pair for 8-9 hours, the Adapt Runners were way easier on my feet. I think the secret is the wider toe box and the differences in the heel-to-toe drop, which is how much your toes drop below your heel.
The Adapt Runner has a roomier toe-box and a zero drop which allows your muscles and ligaments a natural, full range of motion that can potentially improve posture and reduce the impact on the joints. The Clifton 9 has a 5mm drop which is perfectly fine for a run but didn’t provide as much comfort after a long day of walking.
If You Seek Breathability and Lightweight Design ... Flux
One standout feature of the Flux Adapt Runner is its AdaptKnit™ upper, which offers exceptional breathability and a snug, supportive fit through its reinforced stretch knit. This promotes optimal air circulation, keeping my feet cool and dry during long runs and intense workouts. The lightweight nature of the AdaptKnit™ enhances the sensation of running barefoot, providing necessary protection while feeling barely there.
In contrast, the Hoka Clifton 9 feels heavier and less breathable, which can diminish the sense of freedom I look for in my runs.
If You Want More Color Options … Hoka
The Clifton 9 comes in 14 seasonal colors in addition to their five core colors. Flux’s Adapt Runner comes in 17 colors, which is still a big selection but if you’re looking for something specific and funkier, Hoka has you covered.
I have to say, I prefer the look of the Adapt Runner with its super low profile, subtle logo and solid colors. They really go with everything which is perfect because I literally wear them all over the city while running errands, grabbing lunch with a friend, and going for a walk in the park.
If You’re After Durability and Easy Care … Flux
Despite being low profile, low weight shoes, Flux is incredibly durable. I wore them all day almost every day for weeks on end and they aren’t wearing thin at any spot. I also love that I’m protected by the Adapt Guarantee which offers a free replacement for any manufacturing defects within one year of purchase.
You might be wondering how gross my shoes are after wearing them for weeks on end. Well, fortunately, Flux’s Adapt Runner is machine washable with a removable insole which makes them so easy to keep clean. Hoka’s Clifton 9 are not machine washable and require some elbow grease and quite an involved process to clean.
My Ultimate Winner … Flux
After testing both the Flux Adapt Runner and Hoka Clifton 9, my verdict is in. Flux edges ahead with its blend of comfort, versatility, and the added bonus of being machine washable. Price-wise, they're closely matched, with the Adapt Runner at $139.99 and the Clifton 9 slightly higher at $145—both shipping free. While Hoka offers a plush ride, for those who prioritize a shoe that adapts to different running styles and is easy to care for, Flux is my new favorite.
