Our verdict

Because of its high energy return and reliable lockdown, our test workouts show that the Zoom SuperRep 4 from Nike is a suitable partner for HIIT and other exercises that have explosiveness at their core. Given the high levels of comfort that this shoe delivers, this Nike trainer never loses its utility even beyond the four walls of the gym. It is a multi-purpose shoe for the price of one, and we think that it's perfectly suitable for those who are almost always on the go.

Cushioning

Heel stack

Right upon wearing it, we already felt a (very welcome) uptick in height! The midsole of this Nike trainer is just thick!

Scarpe Nike Nike Air Max Bolt CU4151-1 Nero Heel Stack

Using a calliper, we measured the heel to be 29.5 mm thick. This number makes the heel area 22% thicker than average.

Forefoot stack

Just like the heel, the forefoot is on the thicker side. We measured it in the lab, and the calliper gave a reading of 27.7 mm. The forefoot, therefore, is 54% thicker than average!

Scarpe Nike Nike Air Max Bolt CU4151-1 Nero Lifting

While we liked that this shoe made us feel a lot taller, we have to admit that this much stack height made lifting a bit of a challenge. The Nike dunk low кроссовки найк кожаные 41-45р is still the better cross-trainer when it comes to weightlifting.

Drop

With a drop of only 1.8 mm, the Scarpe Nike Nike Air Max Bolt CU4151-1 Nero surely felt flatter than most shoes that we have exercised in. 

Such flatness would have been good news for lifting if not for its insanely high stack height. While having more material in the midsole increased impact protection while running, it also increased the risk of wobbles during lifts.

Midsole softness

Note: a low durometer measurement equals a soft material, whereas a high measurement means it's firm.

Speaking of impact protection, we experienced a lot of it while wearing the Zoom SuperRep 4 from Nike. Hence, we didn't mind wearing it for long periods of standing and claro. 

Our HA durometer pegged the softness of the material at 21.8, making it roughly 21% softer than average.

Insole thickness

There is not much to gush over the insole. It's just as thick as the average insole at 3.7 mm. But it surely complemented the very soft midsole well.

Stability

Lateral stability test

When doing agility exercises, light lifting, and even HIIT exercises, lateral stability was not a problem. 

The sidewalls and the heel counter were responsive enough to keep our feet in their place. There were problems, though, when we started to lift heavier weights. The soft and high platform just didn't do a good job of keeping the wobbles at bay.

Torsional rigidity

For a shoe with a soft midsole, the Scarpe Nike Nike Air Max Bolt CU4151-1 Nero was surprisingly resistant to twists. When we gave it a good manual twist in the lab, we were so amazed by the resistance that it had that we gave it a perfect 5 for torsional rigidity.

Given such observations, we think that using this shoe for prolonged runs won't be such a bad idea. We also enjoyed some level of springiness for our jump ropes and box jumps because of the stiffness of this trainer's base.

In the lab, we used a digital force gauge to measure how much energy was needed to bend the SuperRep 4 at 90 degrees. We found that this shoe needed as much as 33.7N! This number makes this Nike trainer 76% less flexible than average.

We surely felt the inflexibility during our workouts. Doing exercises like planks and burpees that demand a certain level of linear flexibility wasn't so easy with the Scarpe Nike Nike Air Max Bolt CU4151-1 Nero.

Breathability

In all fairness to the Scarpe Nike Nike Air Max Bolt CU4151-1 Nero, it delivered just the amount of breathability we needed. As long as our socks weren't thick, we did not have problems with too much sweatiness.

During our breathability test, we saw smoke rise through the upper material. We also saw a moderate amount of light pass through without much issue.

When examined under our microscope in the lab, we saw that while the upper is closely knit, vents still allow ventilation.

Durability

Toebox durability

Just by touching it, we already had a hunch that the SuperRep 4 was going to be more durable than many of the trainers that we tried. This initial assessment was confirmed by our Dremel test, where it got a score of 3 out of 5 when most trainers don't get anything better than 2.

As can be seen in the picture below, the Dremel cut through the uppermost layer. Yet, it did not poke a hole in the layer after that. This result proves once again that layered uppers do enhance protection from bumps and other forms of physical trauma that we commonly experience while working out.

The heel padding didn't fare any worse or any better than the average. It garnered a score of 2 out of 5 from us.

On the feet, the soft padding felt soft and comfortable. We did not experience it biting into our skin, even if our socks weren't that high to cover the area.

Outsole hardness

When it comes to the hardness of the outsole, the Nike Zoom SuperRep is also just around the average. It got a rating of 86.5 on our HC durometer.

Outsole durability

We performed the Dremel test on the outsole and we saw that it's as durable as the majority of the trainers available on the market today. Our in-lab measurements revealed that our Dremel drilling poked a dent only 1.1 mm deep.

We used it for a couple of sessions outdoors, and it held up quite well. With proper care, we think occasional outdoor usage won't hurt. However, if the programme calls for a lot of outdoor work, we think it's better to switch to a more durable pick such as the nike air max 97 white habanero red white black from Reebok.

Outsole thickness

To the touch, the outsole did not feel too soft nor was it too firm. We had so much fun skipping rope and doing moderate runs in the Scarpe Nike Nike Air Max Bolt CU4151-1 Nero. We just know that these exercises won't put the longevity of the outsole in jeopardy.

Our calliper measured the outsole to be 3.8 mm thick.

Misc

Grip / Traction

The shoe's traction worked as it should. We did not have problems stopping when we needed to.

Tongue padding

The tongue of the SuperRep 4 is just as thick as the average at 5.2 mm. It felt comfortable on top of our foot and it surely helped in securing it (the foot) during shifty movements.

The shoe's bootie structure surely helped with lockdown. We never felt the shoe loosening its clasp on our foot even if we were already doing HIIT exercises.

The laces further enhanced the shoe's clasp on our feet. Containment was surely not a problem with this trainer.

Heel tab

Like many training shoes that we tried, the Nike SuperRep 4 does not have a heel tab. Fortunately, the opening is wide enough to welcome the foot so no problems were putting this shoe on and taking it off.

Removable insole

The insole is of average thickness and it's removable. Hence, it was easy to get rid of it to make way for orthotics or to replace it with something softer or firmer, whichever was needed at the time.
