Summer running has never looked this good. We merged our best selling fabric with the functional design of our Speed Shorts to bring you our Faster Than Light Short. These shorts fit and feel like a glove, with improved sizing adjustments from our Speed Shorts. They are a Summer training staple, and scream runner girl. 



- Our best selling fabric, made for high intensity movement

- Unique 1/2 elastic waistband taper design for maximum comfort around your stomach (no pinching around your stomach) while still ensuring shorts do not budge

- Thigh design ensures spandex do not ride up during movement

- Side pockets, perfectly placed and sized for weightless feel with zero movement. Made for your phone, keys, gels, and more

- No front seam 

- Reflective logo on the back

- Flattering back "V" seam to accentuate the glutes


Inseam measurements:

We do NOT believe that one size fits all, which is why we use a grading method for our inseam measurements. This allows the shorts to look and feel the same on all sizes. 

Inseam Grading of Spandex Shorts:

xsmall- 9 cm

small- 10.2 cm

medium- 11.4 cm

large- 12.6 cm 

xlarge- 13.8 cm



- Runs true to size. If you are in between sizes, we recommend sizing up. 

- Caitlyn is 5'8, has a 26" waist, and wears a size xsmall.

Love Love Love These Shorts!

I bought these shorts for my current marathon, and was not disappointed one bit! They did not move at all, I even ran with my phone and gels in the side pockets and they weren’t pulled down at all. I’m 5’4 around 130/135 lbs and typically wear a size small but went with a medium for these and they fit perfect. Will definitely be buying more!

Don’t walk. RUN to get a pair of these shorts!

These shorts are unlike any other brand you will find. I wore them for my marathon and shorts tend to always rise up in some way but these did not move a centimeter the entire 26.2miles. They are buttery soft and the pockets are so deep and perfect for a phone, keys, gels, etc. The quality of these shorts is worth every penny and I will be recommending these to anyone who is looking for a new pair of shorts. I’m normally a medium in shorts like these but sized up to a large to avoid being too snug. Perfect size!

My favorite running shorts!

These are, by far, the best running shorts I’ve ever owned! I now have these in a few different colors. They fit perfectly, look great, and don’t ride up or down. The pockets are fantastic too, I use them to hold gels, keys, and my phone. These are the best running shorts!

No ride up and perfect length

Love these! Probably my new season racing shorts. They don’t ride up my thighs at all, are very flattering in the cut and the side pockets are wonderful. I’m 5’6” and around 140lbs, my thighs do rub when I run and that usually causes my shorts to ride up, especially on my long run days. But these stayed put through 12 miles easily and where squat proof when tested at the gym as well. Will be buying another pair. I am wearing a medium and they are perfect.


I wear a small in divergent shorts and the faster than light tights, but got these in a medium and they are perfect. I’m 5’4 and about 115lbs.
I usually just wear flowy shorts or the divergent shorts, but the reviews convinced me to try these. They are seriously incredible- I couldn’t believe that they stay put while I’m running- they don’t roll on the thigh or waist.
I reordered more in red.
