Step One Sports Boxers Shoe Review

Perhaps the greatest complement you can pay any sports boxers or undershorts is that you forget you are wearing them. That was certainly the case for me with the Step One Sports Boxers. 

As an endurance runner, avoiding rubbing or chaffing is essential and it’s something I am constantly aware of. I know that if I get it wrong, my race – and probably several days after it – will be extremely uncomfortable.  

So testing out the clothing that is going to cover some of the most sensitive parts of my body is a must before using them in anything more serious. 

The Step One Boxer Shorts filled me with confidence from the first wearing. They felt a good fit straight away and the softness of the material, made from bamboo, was really noticeable. Added comfort and support was provided by the 3D elastic pouch and it is something that really makes a difference. 

A few short training runs and no problem so I was happy using them as I stepped up training distances to five-hour plus runs. These runs coincided with some warmer weather and, as somebody who sweats heavily when exercising, it provided a much better test of the promised wicking and breathability. And I wasn’t disappointed. I was extremely comfortable throughout despite finishing with my short and vests soaked in sweat. 

Running in the Step One Sports Boxers on a 100k Ultra didn’t require any extra thought from me. I was confident they would be fine, and they were. The second half-of that run was in hot conditions. Once again, I was soaked in sweat, but the Step One Boxers did their job. They wicked extremely well, they were comfortable throughout and I suffered no chaffing or rubbing. 

I tested the Step One Sports Boxers through around 30 hours of exercise and they were washed more than half-a-dozen times. They held up really well and still look and feel as good as they did the first time I wore them. 

Sustainability should be an important factor for all of us when we are making choices around sportswear. And Step One deserve credit for developing a product that is made from organic, sustainable FSC approved materials that also performs to the highest standards.

Overall Verdict

The Step One Sports Boxers felt comfortable every time I wore them. A soft material that didn’t ride up at all during exercise. 

The 3D cup provides additional support that’s not always there in the compression type under shorts. 

Wicking was extremely effective during endurance running and events 

After more than 30 hours of exercise and half-a-dozen washes they look and feel as good as they did straight from the packet
