Nurvv Run Review: Smart Insoles That Improve Form

Must read


When I was passing the baton at the Jackson Middle School track in Portland, Oregon, I didn’t give much thought to race conditions or proper form. But running becomes complicated once you start earning the miles. As I started to gain years (and pounds), I learned that good form is the key to pain-free distance.

Tracking forms like the midfoot strike, where the midfoot lands on the ground, and a pace of 180 beats per minute have helped me go from periodically painful runs to almost 6 miles per day. Better form means more efficiency, less pain and more time to focus your favorite podcast. But teaching me good form had its limits; I still had pain in my hip and lower back after those long runs.

The Nurvv race became the answer to my undiagnosed running problems. This is a pair of insoles with built-in pressure and motion sensors that you insert into your running shoes. In the few months that I have run with them they have helped me further improve my form, get rid of the pain and that feeling of tight hips.

Nurvv Run inserts are available in two pieces. There are the soles that go into each shoe, with a support sticking out of the shoe, as well as two trackers – oblong-shaped material housing the intelligence (and battery) that snaps into said supports.

Removing the trackers from the charger and installing them on the brackets is a learning experience. They sit securely, which means you need to grip them properly when removing them from the feeder or mounts. Do it wrong and the force required could break the cable. I almost did it several times.

The fact that they are difficult to climb is a good thing, considering that you travel hundreds of miles with them. Trackers never feel like they’re falling. Metal clips and velcro keep the brackets secure in your shoes, but the whole system isn’t so attached that you can’t easily move them between multiple pairs of running shoes.

Nurrv says its replaceable insoles will last up to three pairs of running shoes, or about a thousand miles if you’re a little tight like me. I didn’t see any degradation during my months of testing. They are also IP65 water resistant, so you can wear them in the rain and in puddles (just avoid waterlogged shoes).

The battery lasts around five hours, making them ideal even for ultra runners, although they will need to be recharged more often.
