Who should buy the Nike Flex geometric 4

Not as minimalist as the Nike Free Train series, the Flex geometric 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 the trainer

As one of Nike’s cheapest training shoe offerings, the Flex geometric 4 may not live up to the expectations of some people when it comes to durability. Reebok offers a Кроссовки найк nike air max tavas, nike lebron 18 low black red bred men basketball.

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.

Comfortable from the first step in

We are happy with the in-shoe feel offered by the Flex geometric 4 from the first step-in. We commend the great fit of the trainer, and we love how good it feels just walking around in it. We even used the trainer for walking around and we experienced no foot fatigue at all.

There are Clash design elements that contribute to the 360-degree comfort of this Nike shoe.

Soft mesh fabric in the upper conformed to our foot shape, giving us a snug fit.

The rounded toe box provided us ample space for our toes to spread out.

Despite being on the minimal side, the Nike Flex foam has enough cushioning that keep each step supported.

The collar and the tongue are both cushioned. What we like about the foam lining is it prevents chafing and blistering, as well as the foot from accidentally sliding out.

The trainer's front area is entirely made of breathable mesh. We confirmed that this is very efficient in letting the heat escape from the shoe.

Light as a feather - this is a pretty accurate description of how the Flex geometric 4 feels on our foot. With its 9 oz (255 grammes) weight per shoe, this Nike is significantly lighter than the average 10.6 oz (300 grammes) among the workout shoes on the market.

The Nike Flex geometric 4 is aptly named as it features deep furrows at the forefoot section. These grooves facilitate proper foot bending to support quick transitions.

In addition, the edges of the outsole sport a rounded design. This construction allows our feet to smoothly transition from landing to midstance, and finally to toe-off. We noticed that the bevelled 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.

The Flex geometric 4 is indeed one of the bendiest trainers on our roster, being second perhaps only to Nike Free Metcon 4. Nike Flyknit Racer Volt OG vs Nike Flyknit Racer Volt 2016.

We assessed the shoe's longitudinal and torsional flexibility as 2 out of 5 (1 being the most flexible).

Your foot feels in geometric of the movement

With the minimal sole and highly flexible design, you can feel the ground much better compared to the more cushioned options.

We highly appreciate this construction as it really makes fast-paced workouts more efficient.

The Flex geometric 4's cushioning is significantly thinner than what you normally see across gym shoes. Its heel stack (19 mm) is 3.2 mm lower than the average, while the forefoot (15.6 mm) is 2.4 mm less.  

Note: We always measure stack height with the insole included. It is 4.1 mm thick in the Nike Flex geometric 4.

Another contributing factor to the surefootedness of this Nike trainer is its fairly wide footprint. The shoe's sole is 111 mm wide in the forefoot and 89.2 mm in the heel. Curious that its forefoot is 1.3 mm and 2.4 mm wider than that of the Reebok Nano X1 and Nike Metcon X respectively.

We felt that the shoe's cushioning was not very soft either. It doesn't compress easily creating a steady platform to rely on.

Not a shoe for weightlifting

We found that the highly flexible nature of the Nike Flex geometric 4 makes it a poor choice for lifting weights.

It may suffice for working out with dumbells and lighter loads, but this is a no-no for lifting-oriented training. See how much the shoe forces the foot to corrugate forward.

Hard to find cheaper than the Nike Flex geometric 4

With the asking price of £70, you can’t beat the price point of this shoe. It is one of the cheapest models offered by Nike, while on average, their training shoes hover around £110.

But despite belonging to the cheap shoe category, we think Flex geometric 4 is good for its price.

But don’t expect much on the durability front

Unfortunately, it’s not the type of shoe that will serve you nice and long. We established the shoe’s frailty when it showed wear after only some time of use. 

Grips well!

The bottom of the Flex geometric 4, which is strategically lined with rubber, gives traction where it’s most needed. It is riddled with triangular treads that provide a multi-directional grip on both indoor and outdoor surfaces. We discovered that it works great for cutting and other side-to-side movements.

There is no full-length rubber outsole used on the shoe, keeping its weight to a minimum.

It is a sleek one!

We are happy with the clean, athletic style of the Flex geometric 4 which is so easy to match with various outfits.
