About FitKnicks
FitKnicks was created for women who train hard and want underwear that keeps up. If you have ever dealt with visible panty lines, rolling waistbands, “butt bulge”, chafing, or those small but confidence-killing leaks that can happen during heavy lifts, sprints, skipping, or a long session in tights, you are not alone.
Nice to meet you
I’m Maddi (competitive bodybuilder, powerlifter, and boxer). After years of searching for underwear that actually solved these problems (and coming up empty), I decided to build it.
FitKnicks is underwear designed specifically for activewear, so you can focus on your training, not what’s happening under your leggings.
Our mission
Help women feel strong, comfortable, and confident, every rep, run, and rest day
Our mission is simple: create underwear that supports active women physically and mentally. That means better design, better materials, and a brand that talks honestly about the stuff many women are told to keep quiet.
OUR VALUES
We keep it real
Bodies do normal body things. We are not here to shame anyone. We are here to design solutions and talk about them openly.
Performance without compromise
You should not have to choose between looking seamless and feeling supported. FitKnicks is built to perform and to look good under gym wear.
Designed for real bodies
Which are varied and diverse (and ain't that beautiful!) We design for movement and real fit, with an ever-expanding range of cuts and sizes.
Confidence is the point
We're here to help women feel better moving. The goal is feeling comfortable walking into training (or out the door) knowing you are supported.
Going Public on Pelvic Health
Pelvic health should not be a taboo topic, especially in fitness spaces. At FitKnicks, we are here to help normalise the conversation and support women with practical solutions that make training feel more comfortable and confident.
Our leakproof styles are designed for light leaks and peace of mind, so you can focus on your workout, not what is happening under your leggings.
