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.

Finally got me one of these silicone rings to wear at times where I don’t want to wear my diamond rings.

LOVING my new silicone ring. I had actually been on the lookout for one. I love my wedding ring, but the design of it often accidentally scratches the kids because I'm lifting them so much or it gets tangled in their hair.

Perfect fit.

My white gold band is 6.5. I ordered a size 7 silicone ring and it fits perfectly.

this is beautiful

Let me start off by saying, this is beautiful! It has a tiny, tiny bit of sparkle to it which makes the blue color is absolutely stunning. It’s thicker but not bulky. It feels very sturdy, yet soft and comfortable. Unlike other silicone rings, this does not feel or look cheap.

I had ordered this exact one for my husband before and loved it so much that I wanted one as well. I’d been waiting for Knot Theory to release this in a smaller size (the men’s sizes were way too large) and I’m so glad they did! Hands down my favorite silicone ring!

I wear a size 5 and it fits wonderfully!

Nice ring.

Nice ring. Thinner than I was expecting, but that means it's more flexible. It's a nice color too. He likes it and it will be safer for him to wear at work. Very anxious to see how it holds up!

Color looks metallic even though it is silicone. Great quality and perfect for when I can do BJJ and still wear a wedding ring.

Satisfaction

I am satisfied with the look and feel of the silicone ring on the finger. The reason I tried silicone ring was - to find an alternative ring for a person who never had worn anything and metal ring would be too much

Looks great and feels comfortable. Arrived quickly for how far it was coming and nicely packaged. It was bigger than expected.

Arrived fairly quickly considering how far it was coming. Love the look of it- I wore it for a couple of weeks solid and it still looked and felt good. Sizing is bigger than expected, even when I bought down a size, but was fine. Securely packaged.

Love it! I was having a reaction to my wedding ring and can't wear it right now. Decided to replace it with a silicone ring that was in a similar. So happy to be able to wear a ring again!

Wedding set

Purchased as a replacement wedding set. My husband's job requires non metal jewelry.
This was perfect and comfortable.
I purchased a matching set for me.
Love them.

Item is really good. Delivery was slower as it came from America to the UK but I was prepared for that before I ordered it.
