Flow from studio to street in the PureFlex High-Waist Bootcut Leggings. Crafted from our upgraded, buttery-soft PureFlex fabric—92% GOTS-certified organic cotton and 8% spandex—these leggings deliver sustainable comfort with a flattering flare that moves with you.
Designed for fitness enthusiasts and everyday wearers alike, they offer comfort, performance, and sustainability in a flattering bootcut silhouette that elongates the legs and pairs effortlessly with sneakers, boots, or barefoot flow.
Size and Fit
PureFlex leggings are garment dyed and pre-shrunk, so the fit is true to size, wash after wash. Choose the size you normally wear. Sizing down stretches the knit thinner and reduces opacity in deep squats, so we do not recommend it. The 92% GOTS-certified organic cotton fabric is thicker and more matte than synthetic leggings. Full measurements are in our Sizing Chart.
About the Garment
Crafted in our small Los Angeles factory, the PureFlex Bootcut Leggings are Made in the USA. Every step, knitting, cutting, sewing, dyeing, and packaging, done locally to reduce environmental impact. These leggings blend 92% GOTS-certified organic cotton with 8% spandex for a supportive, non-sheer fit that moves with you.
Sewn with 100% cotton thread for a fully polyester-free construction, they're designed to be gentler on the environment and your skin. Independently tested for PFAS by Applied Technical Services, an independent testing laboratory: no PFAS detected, with total fluorine below 2 parts per million (October 2024). The subtle flare from the knee down adds style and freedom of movement, making them ideal for yoga, running, or everyday wear.
We had our bestselling leggings independently tested for PFAS by Applied Technical Services. Total fluorine, the limiting marker for the entire PFAS class, came back none detected at below 2 parts per million.
The report covers the main fabric of our organic cotton leggings, tested in October 2024, against a current industry threshold of 100 ppm. We publish the result rather than a blanket claim.
Why go the extra mile? PFAS are synthetic chemicals used to make fabrics stain and water-resistant, but they’re also known as “forever chemicals” because they persist in the environment and accumulate in our bodies. With PFAS linked to health risks, we made it our goal to guarantee skin-friendly comfort that eases your body and mind.
We use no DWR coatings and no fluorinated finishes anywhere in our line.

Kicking myself for not getting these sooner!! They're so comfy, breathable, and flattering. I love that they're cotton and that I'm supporting a small, family owned business
I absolutely love this style of leggings! I'm 5'8" and the tall fit worked great for me. If anyone remembers the Hard Tail style flare legging, these are replacing that nostalgic style for me :)
I would buy these pants in a million colors if they offered it. Ticks all my boxes as a picky, short girl. 1) organic cotton, a must. no more room for toxic plastic leeching. 2) varying inseam sizes, I'm 5ft tall and it's always a disaster trying to find pants i'm not stepping on (i got 25" and it's PERFECT). 3) the waistband width is a DREAM, no cutting into tummy rolls, just enough support but not where I'm suffocating from compression 4) BUTTERY SOFT material 5) great customer service
Purchased this for my girlfriend for Christmas and she absolutely loved it. We highly recommend the leggings, shorts, and tops and will definitely be reordering. We really appreciate that everything is GOTS and third party tested. The bundle deals were great, the fabric quality is excellent, and the fit is spot on. Overall a great experience and we highly recommend this company.
Very cute and comfortable boot leggings! My main driver was the non-toxic labeling of the company, especially as we sweat while working out. Love that it’s cotton. It is thin material but able to workout in. I’m hopeful it’ll hold up. The style and cut is very flattering. The top is also PuraKai - one of my now favorite tops for working out and walking. It’s also thin, but works well and is nice. The materials of the clothing is hand wash and air dry. Also, they are very responsive and genuine when you email, so I definitely support them!
The pants are a bit snug around thighs but otherwise fit well. Delivery took awhile but I understand that the item was being manufactured when I ordered.
Customer service is great. I love the fit of the leggings, and the material. However you could do away with the front seam and the weird rise on the waist. I was under the impression that these were normal high rise from the photos on the website, but the ride comes all the way up past your ribs with the option to Foldover the waist. I decided to keep these because the pros outweighed the cons, and this is a small business, which I like to support. Please take in consideration making a shorter rise that you don’t have to Foldover, and taking the front inseam out

Hi Rylee -
As a small family business, we are grateful for your support and understanding. We make a mid-rise legging, and we plan to do a bootcut version in 2026.

The fit is good. The waist band fits nicely. The bootcut cut is good. Fitted through thigh and flare just enough. As these are the 2.0 bootleg, I thought that they might be a little thicker so they're not see-thru, BUT alas they are completely see-thru ... making these too expensive for a generic cotton bootleg legging. Comfy but not worth it for me. I am 5'4", 33" waist, 41" hips, I ordered the large. The fit was perfect. I'm a petite, curvy, athletic build. I normally wear a small in Athleta leggings. In retrospect, I wish I ordered the longer length. I ordered the regular, which is 29.5", barely long enough to look flattering. A little longer would give me a better proportion and look slimmer. Sometimes I like to wear my bootcut leggings with my platform sneakers but can't with these. Also, I dance, and these are too short to wear with my dancing heels.
I do love the fabric, feel snd and style but they’re small on me. They end up short because of my size 5’8 200lbs. Just a slightly more generous amount of fabric would have been 100% perfect. I just saw you have xxl so next time.
Love that these are organic cotton. I sized up to get a more comfortable, less compressive fit - but even doing so, these were super tight. Not what I was hoping for, so I returned them. In my opinion, these run 1-2 sizes small.
They're too long even though I ordered the petite. And they smell moldy. I'm hoping that if I wash them two or three times before wearing them it will go away.
