I already had the ultra boosts from 2 years ago and I bought these to do a comparison. The padding is definitely smaller and flatter, so it gives less shape when you look on the side. It gives the same amount of lift and cleavage in my opinion. The only difference I noticed is just that when you turn your body to the side, it gives more of a "natural" result. So if you are looking to increase the shape but don't want that boob job vibe, then this is probably the one you should get.

If you are unsure of your bra size, please measure your bust and contact us with the measurements.
For sizes 34F and up, our Demi Boost Inserts (double push-up) are available in sizes up to 34I and our Invisible Lift Inserts (lightly padded) are available in sizes up to 34M.
Please note that results may vary depending on breast size and shape. Results will be similar to a double push up bra. BOOMBA’s padded inserts work best with natural breasts.

DESCRIPTION
Our slimmer take on the bestselling Ultra Boost. This lift still gives you noticeable enhancement and support, minus the bulk. Gain up to 1 cup size instantly with a subtle, everyday aesthetic. Great for when you want visible results that don't announce themselves.
Unlike adhesive-backed sticky bras, Getboomba inserts rely on garment support and won't stay in place independently. Wearing them requires snug, structured, and form-fitting clothing.
For optimal sizing, we suggest selecting your actual size. Only go smaller if you fall between two sizes.
Do you have implants? Check our FAQ to find out whether they work for you.

FAQs
Preparation is key! Before using BOOMBA inserts, make sure your skin is clean and dry. Avoid applying makeup, oils, lotions, or other body products, as these can affect the adhesive’s ability to stick properly.
Start by putting on your clothing item. Then, place the inserts inside the garment without touching the skin. Finally, scoop your breasts to your desired position and stick the insert along with your top onto your breast to secure.
Unlike traditional inserts, BOOMBA inserts are sticky on both sides, which means it sticks to your clothing and to your skin for extra security. Preventing nipple slips and easily staying hidden under clothing.
BOOMBA inserts require no sewing to stay in place! Just stick to your skin and to your top! They are easily interchangeable between different tops and dresses.
BOOMBA inserts are designed to be reusable for up to 40+ wears with proper care. To extend their lifespan, gently clean the inserts after each use and reapply the protective films right away. This helps prevent dust, lint, and other particles from sticking to the adhesive surface and ensures long-lasting performance.

super impressed by how sweatproof these are. I went for a hike in the heat and these inserts stayed exactly in place the entire day.
Ultra Boost (Lite) InsertsBoobs got saggier after having kids and I have been hunting for something to fix it and these do the job perfectly. They lift and look natural and doesn't cost me an arm and a leg. I love that it basically gave me a boob lift in seconds.
Ultra Boost (Lite) InsertsThe sticky bra came in super bougee packaging. The unboxing experience was very nice. The product itself is also really good once you learn how to use it correctly. I kept sticking it to my skin first and only realized after reading the instructions card that I was using it wrong. After learning how to use it correctly, the results are insane!
Ultra Boost (Lite) InsertsI like how its padded but the insert itself is not heavy (I got size H) and does not drag down your top like a traditional silicone insert. It's quite lightweight and comfortable, I didn't even notice I had them on until I got home to remove them.
