2 reasons not to buy

  • This Inov-8 model carries a high price tag, which is above average among training shoes.

Good to know

What is it good for? The shoe was designed as a CrossFit-ready piece, keeping today’s gym challenges in mind:

  • all sorts of jumps, be it up-and-down or side-to-side
  • squats and other weightlifting exercises
  • rope climbing
  • short sprints and treadmill sessions

Durability of the world’s strongest material. Inov-8 has been placing graphene at the heart of its most recent trainers, including the G 300. It is incorporated into the rubber outsole, making it twice as durable as the regular rubber.

Grip and abrasion resistance on rope climbs. While the Rope-Tec is included in all of the brand’s training array, it is significantly extended on the G 300. This time it features added blade-like lugs to bite the rope even better.

Toe protection. The extended piece of rubber at the front forms a lip to protect the toes from painful bumps.

Forefoot flexibility. A wide Meta-Split groove crosses the forefoot part of the sole. It makes this area more pliable to let the foot bend freely.

Stability for weightlifting. Hidden inside the heel portion of the midsole, a Lifting Stabilizer comes into play when you grab some weight. It is also infused with graphene to provide rock-solid support and eliminate foot wobbling.     

Cushioning for jumps and runs. While the heel remains firm, the forefoot section houses some responsiveness for the more active parts of a workout. 

Comfort footbed. Extra padding is delivered through the Boomerang footbed. It can be easily removed if preferred.

Form-fitting and breathable fabric. The bootie-style upper of the G 300 employs a fully-engineered knit fabric. Because it is a single-layer material, it offers a high level of breathability, stretches easily, and keeps the shoe lightweight.

Supportive heel. The rearfoot area, on the other hand, features a tougher, thicker fabric with extra padding and a heel lock design. It prevents the heel from slipping out of the trainer.

Midfoot cage for support and protection. The TPU panels on both sides are pulled together through a lacing system, forming the shoe’s ribcage. It contributes to the overall foot containment, lateral support, and abrasion-resistance.

Pull tab for easy wear. A loop is attached at the front apex of the trainer. It helps the wearer to don a pair a bit quicker.

While the G 300 shines in the stability department, its higher platform may not be appealing to those looking for maneuverability. The G 235 v3 model can be a great alternative if you are looking for lighter and more agile footwear.

Below are the key advantages of the G 235 v3:

Price. The retail price of the G 235 v3 is $20 less than that of the G 300.

Weight. With 235 grams, the G 235 v3 is one of the most lightweight models not only from Inov-8 but on the CrossFit market in general. 

Flexibility. It has also been described as one of the most flexible models.

Grounded feel. The 235 has a thinner sole and a lower drop, helping the wearer feel more in control.

Durability. Just like the G 300, the 235 got released in a G version, meaning its outsole now incorporates graphene.
