Feel Our Difference

CURVED FOR ALL-DAY COMFORT

Knot Theory’s signature curved interior contours your finger for a more comfortable, breathable fit - without the pinching and “finger muffin-top”.

SMOOTH. CLEAN. BREATHABLE.

No grooves to collect sweat, lotion, and dirt. Our smooth, curved interior encourages airflow, reduces moisture buildup, and rinses clean in seconds.

REFINED, NOT RUBBERY

A sleek, thoughtfully proportioned profile - never bulky, flimsy, or tire-like. Every Knot Theory ring undergoes rigorous quality checks, because silicone shouldn’t mean settling.

have only had them for a day but the colors are great, both rings ordered fit well and the silicon is comfy and stretches nicely, perfect for a cheap band

I love wearing silicone rings! I want comfort from my regular wedding ring where I don’t bang it around or when my fingers swell.

I love the engagement ring and wedding ring that my husband got me. However, I am a work from home mom with an 8 month old that grabs and pulls everything, a lab that is well a lab, and am trying to work on my self every day. I needed something that just worked for every day use that wouldn’t cut the gums of my child or dog when they decide to bite. Decided to try this ring from Knot Theory and it doesn’t disappoint. It is super comfortable and withstands day to day life. Might have to look into some more color options.

The shop was great and sent me one free resized ring when I did a terrible job choosing my first size. The ring is beautiful and the shine classy. Will be buying from them again

I have had many silicone rings now, and by far this has to be my favorite.
The shipping was very fast, let's begin with that.
But the feel and fit of this ring is amazing. It's so comfortable I often forget I have it. I absolutely love the color. It's dark, but still vibrant.
And since I knit, there isn't metal or gems for the yarn to get such on, so that's a big bonus for me.
Just a great piece of well made jewelry.

Took a little long to get here, but I love it. Well worth the wait!

Absolutely love this ring. It doesn’t even feel like I’m wearing anything. I kept bruising my finger at work with my wedding ring set so I got this to prevent that. The ring feels smooth to the touch and fits perfectly.

I just got engaged a few weekends ago. I work in a hospital setting and was worried about wearing my engagement ring. My fiance told me about silicone rings. I found this on Etsy and decided to get one. I wanted it the same color as my ring. I've been wearing it for a week and I absolutely love it. It fits amazing and stays on nicely *I constantly wash my hands so I'm happy it doesn't stain my finger and stays on. A must get item, if you're worried about the same thing. I love the color.

Super fast shipping! The ring is comfy and beautiful. I wish there was one size smaller than a 4 because my fingers are insanely skinny. But this will do just fine- it’s not coming off easily. Thanks!!

Just as described! I love to use this for working out so I don't ruin my ring.

Super cute & I do believe it’s just perfect for my job. Wearing gloves all day, I’m afraid that my wedding set will puncture the gloves. Plus it’s purple…..my favorite color 😍

I ordered this ring for my husband. Seems I should have done so long ago! He loves it. He says it feels like he's not wearing a ring at all so it took some getting used to but he really likes it.
