Walk into a Crossfit Box and you’re likely to see a lot of Nike, Reebok and Nobull sneakers. While Reebok was first to the Crossfit training shoe game in 2011, Nike followed suit in 2015 and has since crafted some exceptional Crossfit shoes. The latest is the Nike Metcon 4, released in January, which brings an upgraded appearance along with upgraded performance. Here’s how it compares to previous iterations, plus the light under which it really shines.
The Good: The Metcon 4 takes basically all of the best features of the Metcon 3 and adds just a few tweaks. The shoe is more durable and works for both weight lifting and sprints. Design features like the interlocking pattern on the sole look cool, plus they grip exceptionally well for sled pushes and pulls. The sole also allows you to crush 100-meter sprints. The 4mm offset means your heels are close to the ground to allow for a stable launch for tuck jumps and power cleans — as well as provide firm support for deadlifts and overhead presses. The dual-layered sock liner lets the shoes breathe a bit, and the added sixth loop for the laces enhances fit and comfort.

Who They’re For: Anyone who lifts weights, frequently visits a Crossfit Box, takes athletic conditioning classes or boxes. The shoes perform well in all conditions where distance running and jumping aren’t integral to the workout. For the average gym-goer, this is a great shoe. It shines on all weight-lifting machines, as well as with free weights.
Watch Out For: While the Metcon 4s are updated to be a bit more flexible than the 3s, it’s still not a sneaker I’d want to grab for a run. The toe box flexes back toward the tongue, but it’s built to be a more rigid shoe — offering the support you need for gym exercises.
In terms of fit, heel slip was something the Metcon 3 had a slight issue with, and while Nike has added an additional lace loop to tighten the fit, it’s still something to watch out for. If you’re used to working out in standard running sneakers, these shoes are built differently, so it might take a little while to get used to them. When I first put them on, I thought they were snug, but after three months of use, they’re comfortable and feel normal.
