Print Story - Summit
design evolved from a conversation around "mountain logic" — how a runner forms the link between earth and sky through their ascent and descent of vertical terrain. Look for the ladder in the print, symbolizing that connection and transcendence.

Print Story - Spray Dye

The Spray Dye print capsule is inspired by the distinct differences of each waterway on this planet, and the greater interconnectivity they all share as a singular body.

care instructions

Wash before first use on cold with like colors

Tumble dry low

Heads up — some color bleed may occur
Color bleed, especially with darker colored nylon/spandex blends, is common and could stain light colored garments if washed together.


Groundwork Knit is made using a premium grade nylon that has a significantly tighter woven filament than standard synthetics. Tighter filaments mean less microfiber shedding in the wash-cycle, plus greater durability of the garment (longer lifespan, more wearing).

Groundwork Knit fabric is also bluesign® certified meaning it is free from harmful chemicals and is fabricated in a way that meets a high environmental standard.

Good mobility

I'm 5'2 and 130 pounds. I ordered a medium. I definitely needed to use the drawstring to keep them in place, but with the drawstring tied properly, these were comfortable and didn't move or need adjusting on a 10 mile run. I don't like to use side pockets for holding my phone, but the back waist pocket is big enough for my phone (have only used this carrying option during shorter runs, though).

Haven't written a review for leggings in a while

Ordered these mostly because I've been obsessed with the spray dye print for months. I didn't really need new running tights since I wasn't unhappy with the ones I already own, but I'm so glad I bought these. Went for a 5 mile run the day I got them, and they exceeded my expectations. They were supportive without being noticeable, and as bonus, the fit is very flattering. Immediately washed them and wore them for an 8 mile run the next day, with my phone in the side pocket. I didn't feel my phone move at all, but I did notice the top of the pocket stretched out by the end of the run from grabbing my phone. It looks like it might snap back into place, but that's my only (minor) complaint. Otherwise, I feel ready to replace the rest of my running tights with these. They're light enough that I could see myself using them for warm weather runs too. For size reference, I'm 5'2 and 117lb and the small fit perfectly.

Janji Groundwork

I love these tights. They are light, have compression and have pockets. So great, I ordered a second pair

Nina Leon
Favorite Running Leggings

Lightweight with just the right compression. Pockets are perfect. Do not feel keys or phone when running. And love the burst of color. These are perfect running tights.

Best leggings I own! Hands down!!

These leggings don’t look too much different from other leggings in general, but let me tell you!!!
These leggings are LIFE!
I now own them in blue and green and plan to buy the black and multi colored ones as well because not only are they just the most comfortable leggings I own, but they are the most functional.
I run in them everyday with my phone in one pocket and my keys in the other.
The compression is just enough to make sure everything stays secure and they even keep my shin splints at bay.
The fabric is buttery soft and I just can’t imagine going for a run anymore without them.

Jennifer Manville
best leggings/tights ever

Don't sleep on these. I live in leggings and these 7/8 Groundwork tights are my favorite of all time. I use them for everything. Running errands, hiking, cycling, yoga. They are so soft and comfortable with great support and structure around the waist. The side pockets are positioned perfectly and not bulky, which is always my concern with pockets on leggings. I've bought several pairs of these, and even gift these to friends. They're that good.

Cynthia Ramos
So soft!

So happy about these leggings. So soft, comfortable and the fit is perfect. I’m 5’4” 120 lbs, the size small is a perfect fit. The waistband is perfect as well, not too high (which I like) and love the pockets. I need these in every color!!

I wish I could wear this everyday

I don’t actually use it for running. Though I prob will. I’ve been wearing them under skirts to keep me cool but covered (and with pockets). It’s a bit roomy though I’m a medium in the AFO shorts
