Updates to Reebok Ultra Circuit TR ULTK LM

  • The Reebok Ultra Circuit TR ULTK LM is built specifically to keep up with the physical demands of Les Mills workout sessions. It is intended to be used for strength training, cardio, high-intensity exercises, body combat and more. The trainer is equipped with materials that are lightweight yet durable, stable, and supportive. The upper is made of the Ultraknit, a single piece of fabric that keeps the foot securely in place but also allows it to expand naturally.
  • The midsole uses carbon ethylene-vinyl acetate (EVA) foam. This compound is intended to be soft to attenuate shock but also retain its shape to provide a steady platform. Part of the midsole, called the S-Frame structure, wraps the lower portion of the upper to enhance lateral support.
  • The rubber outsole protects the bottom of the shoe. This hard-wearing material features a geometric tread pattern that promotes flexibility and provides traction on different types of surfaces.

Reebok Ultra Circuit TR ULTK LM size and fit

The Reebok Ultra Circuit TR ULTK LM is designed in both men’s and women’s versions. It is available in US sizes 7 to 14 for men and 6.5 to 10 for women. The width comes in a male D - Medium profile and a female B - Medium. For people unsure of their shoe sizes, clicking on the Size Chart link on Reebok’s product page opens a pop-up window that provides a quick tutorial on how to measure one’s feet in order to obtain an accurate trainer size.


The underside of the Reebok Ultra Circuit TR ULTK LM is lined with rubber. This compound is developed to be hard-wearing to endure working out on indoor and outdoor surfaces. It has numerous sippings that create geometric patterns throughout its length to facilitate natural foot flexion. They also promote multi-directional traction. The rubber extends to the front, protecting the toes against bumps during exercises like burpees.


The midsole of the Reebok Ultra Circuit TR ULTK LM employs the carbonated EVA foam. This material is engineered to be soft to attenuate shock and keep the foot comfortable. Though it is lightweight, it is designed to be durable and keep its shape during high-impact training.

On top of the midsole is the S-Frame. This component extends upward, wrapping the perimeter of the upper to deliver support needed for side-to-side movements.


The upper of the Reebok Ultra Circuit TR YLTK LM is made of a one-piece Ultraknit fabric. This proprietary knitted material provides seamless coverage, so that nothing could irritate the foot while exercising. The low-cut design promotes freedom of movement and quicker transitions.

The footgear features a dynamic lace-up system. The eyelets are set in varying distances with each other, ensuring better lateral coverage when the laces are cinched.

Synthetic overlays are found on the toe box and the heel. They form a protective layer that prevents the underlying knit fabric from getting damaged. At the rearfoot, it also serves as a heel counter that keeps the back of the foot steady during dynamic motions.
