PICcircuit 2PCS for Stanley Boot, Silicone Bottom for Quencher Adventure 40oz 30oz IceFlow 20oz 30oz Bottle&for Hydroflask Tumbler 12-24oz for Stanley Cup Accessories Avoid Scratches&Noise

First they fit the Stanley ice flow 32oz. If that's what you're looking for this will work. They do the job and protect the cup. Worth the money. They slide in easy and come off for cleaning but not to easy. I'm happy with them.

Worked great, fits in the car coaster well, looks good

Received order quickly. Love the colors. This boot really helps to grip the surface it is set on. No more toppling over!

These silicone boots were perfect for my Stanley iceflow 20oz bottles. My bottle had taken a few falls and had become wobbly, which is why I purchased the boots. The boot immediately cured the wobble and matches the color of my cap near perfectly. It has a smooth finish and feels easy to wipe down or wash. I'll probably be purchasing in different sizes for our other bottles.

This boot fits my 40 oz Stanley perfectly. It’s nice to not have the metal cup “clanking” every time I put it down. And it protects the bottom of the cup.

Dearest Readers,I have been informed of a curious contraption known as a "boot" designed to protect one's beverage container from the perils of everyday life. This particular boot is crafted from silicone and promises to shield one's water bottle from unsightly dents and the dreaded clattering sound that often accompanies its placement on a surface.While the concept is sound, it appears this particular boot is not without its flaws. It is said to be a loose fit for the Hydraflow water bottle, a circumstance that could lead to unfortunate accidents while in transit. Moreover, the boot's tendency to become lodged in cup holders poses a potential hazard to the driver.Perhaps a more tailored solution is required for those seeking optimal protection for their beverage vessels with the Hydraflow brand.Yours truly,Lady Whistledown

I need a replacement bumper for my thermoflask. This one fit my 14oz flask and also the bottom of an insulated cup. Less expensive then the one from the manufacturer.

I carry a tumbler with me almost everywhere and I was noticing that the bases were getting scratched up and looking a little rough. These are the perfect fit for my 40 oz tumblers, and though they are a bit snug in the car cup holders they are still able to fit. They are good accents for my cups, and i just rinse them out after using. I have found the best way to put them on is to turn them inside out and kind of roll them over the base of the cup. Definitely worth the $$.
