Profile of the Nike In-Season TR 9

The 9th iteration of the In-Season TR line strays very far from its predecessors in terms of style and technologies.

This time around, Nike employs a dual-density Renew midsole which has previously been used in some of the brand’s running shoes. It is meant to make the trainer more efficient for workout sessions that involve cardio, running, and light to moderate weightlifting. 

Another notable feature is the wide gore strap at the midfoot. Placed on top of the laces, it serves to hold the foot steady throughout the most intense lateral movements.

At the same time, this In-Season trainer remains one of the most lightweight training shoe options for ladies.


There is no dedicated full-length outsole in the In-Season TR 9. This is one of the key contributing factors to the shoe’s lightweight nature. Instead, the trainer relies on the targeted rubber pods which add durability and grip where they are most needed.

The entire platform features a recessed tread pattern that keeps the surface flat. It helps to create a more flat ground contact to promote stability for weightlifting.


At first glance, it may seem like the shoe has a very thick sole unit. But in reality, the foot sits rather close to the ground. It’s the raised side panels that make the midsole seem so big. They extend upwards, creating borders on both sides. Such construction offers foot containment during lateral movements.

The Nike Renew serves as the main cushioning component in the In-Season TR 9. It is a dual-density material that fuses a responsive foam for bouncy jumps and a firmer foam for stability. It also makes the trainer a bit more friendly for short runs.

The Comfort Footbed puts a finishing touch to the shoe’s underfoot padding. This memory foam sockliner adjusts to the individual’s foot shape for extra comfort.


The entire upper of the shoe is wrapped in a breathable mesh fabric. It creates a soft coverage for the foot while making sure the foot chamber stays aerated.

The 9th version of the In-Season TR is equipped with a large midfoot strap. Made of an elastic gore material, it remains stiff when support is required but also stretches with the foot when necessary (for example, when the shoe is being put on). That way it helps to deliver a more adaptive foot containment.

The lightly padded tongue and collar and an extended heel apex also contribute to a secure lockdown. They hug the ankle area to prevent the footwear from slipping off.
