Our verdict

The Flex Control 4 is one of the cheapest workout shoes from Nike that we ever landed and yet, it doesn’t fall short of the essentials we need for a moderate gym session. Coming from the Nike Flex series, we found that the trainer feels extremely flexible to promote agile, multi-directional movements. This is not to mention how light and comfy it feels on the foot overall.

Pros

  • Comfortable in-shoe feel
  • Lighter than average
  • Very flexible
  • Foot feels planted
  • Budget-friendly
  • Good grip
  • Simple aesthetics
  • True to size

Cons

  • Durability issues

Who should buy

Not as minimalist as the Nike Free Train series, the Flex Control 4 has some cushioning to it. You are likely to appreciate this trainer if you are after the following:

  • an entry-level shoe for a very low price
  • a light and flexible workout shoe for aerobic exercises, plyometrics, and similar
  • a no-frills pair of school gym shoes
  • footwear that can be doubled for casual, everyday wear

Who should NOT buy

As one of Nike’s cheapest training shoe offerings, the Flex Control 4 may not live up to the expectations of some people when it comes to durability. Reebok offers a Reebok Nano X3, which is versatile and great for agile workouts. It is a bit more expensive yet also more durable.

And if you are looking for a shoe that can handle some serious training sessions that involve lots of weightlifting, we recommend checking out the more premium-level Nike Metcons. Some of their earlier iterations are offered with a generous discount.

Flexibility / Stiffness

New

The Nike Flex Control 4 is aptly named as it features deep furrows at the forefoot section facilitating unhindered foot bending.

In addition, the edges of the outsole have a rounded design which allowed our feet to smoothly transition from landing to midstance, and finally to toe-off. We noticed that the beveled edges on the lateral and medial sides of this Nike workout trainer also facilitate fluid side-to-side agility.

Generally, we can describe the ride of this shoe to be very smooth.

Using a shoe flexing tester, we measured exactly how much force it takes to bend the Flex Control 4 by 30 degrees in the forefoot. At 10.1N, it indeed required less force than the average trainer!
