Nike LeBron TR 1 Green Strike: reviews, sizing and how to wear LeBron's first training shoe
What if the loudest shoe in the gym was also the one with the best grip? The Nike LeBron TR 1 Green Strike is the first training shoe Nike has developed with LeBron James, and it lands in an acid green that's impossible to ignore. Here's what people already training in them are saying, which size to get and how to style them.
The Nike LeBron TR 1 Green Strike (style code FJ6151-300) is a training shoe built for the gym, weights and circuits. It ditches the strobel to bring your foot closer to the foam, runs a waffle outsole with a herringbone pattern for grip and comes in the Green Strike/Fir/Green Shock colorway, released in June 2025.
What is the Nike LeBron TR 1? LeBron's first training shoe
LeBron's signature line has always revolved around the court. The TR 1 opens a different chapter: a shoe for the work that happens off the court, in the weight room and in the conditioning sessions James has been turning into viral content for years.
According to Nike, LeBron asked for two things: real performance in the gym and a look that holds up all day on the street. That's why the silhouette feels low and stable, with a design that doesn't clash with a technical tracksuit outside the gym.
LeBron TR 1 tech: what's under the green
What makes this trainer interesting is in the details you won't see in an Instagram photo. These are the key points:
- No strobel: the team removed the bottom layer of the upper so your foot sits directly on the foam for more responsiveness.
- Cushlon cushioning: Nike adds it for comfort on every rep without losing stability.
- Bootie construction: it wraps your foot like a sock and leaves room for the swelling that comes with a long session.
- Lace cables: they help lock down the midfoot when you tighten the laces.
- Exclusive inverted waffle outsole: big lugs with a herringbone pattern and flex grooves in the forefoot, with traction placed only where it's needed.
Nike LeBron TR 1 reviews: what people training in them say
The reviews pretty much agree. What comes up most is the grip and the planted feel: traction responds well on gym floors, on short treadmill stints and in quick changes of direction.
What people like
- Stability for weights and cardio circuits.
- Comfort that comes fast: the fit settles in after one or two sessions.
- A design that works just as well outside the gym.
Good to know
The fit is snug. Several users with very wide or flat feet find them tight, especially with thick socks. It's not a flaw, it's a trainer built to hold you in place, but it does affect which size to choose.
What size should you get in the Nike LeBron TR 1 Green Strike?
Nike says the model runs slightly small and recommends going up half a size. Reviews add some nuance: if you like a snug, locked-in fit, your usual Nike size can work.
- Between two sizes or wide feet: go up half a size.
- Narrow or regular feet and a firm fit: your usual size.
- Thick compression socks: better to go half a size up.

How to style the Nike LeBron TR 1 Green Strike
The acid green calls the shots, so the rule is simple: make it the only accent in the look. It works best over neutrals.
- Gym look: black training shorts, a gray tech tee and white socks.
- Street: a full black technical tracksuit with the sneakers as the only color.
- Light monochrome: gray joggers and a white sweatshirt so the green pops on camera.
Avoid pairing them with other neons; two strong colors compete and the outfit loses impact.
