It's great!
Does what it's supposed to. I was tired of too many dents along the bottom edge of my hydro flask, so this boot is great for preventing that.

Keeps flask from sliding
Love the boot! Bought 2 cobalt boots, mine matches the cobalt Hydroflask, the other looks great with the glacier blue flask. As other reviewers have stated, these help keep the noise level down. Also helps keep the Hydroflask upright in my tote bag , and keeps it from rolling out of the cupholder in my car. Great purchase, glad we got them!

Fills a Need
Ended up damaging the bottom of my original bottle. Not sure how it happened actually. This boot protects the bottom of the bottle and allows it to stand upright easily. Only complaint is that it does add some girth to the bottle which makes it more difficult to slide in and out of my back pack sleeve. I assumed this would be the case though and was a trade off I was fine with. Material feels durable and fits snug on the bottle.

super cute
I didn't realize how great this would prefer my life! The bottle is so much quieter which you don't realize how annoying it is until you get a boot. Plus looks super cute and fun.

Covers dents well
I bought this a month ago to cover up the dent in my hydro flask that I got not even a week after I bought it. It works very well it’s self, but the bottle is very disappointing that it can be so easily dented especially for how costly it is. I wish I could say this product will last me because it works well just very disappointing.

Great Addition
This boot is absolutely great. I have the 40oz bottle and the boot fits perfectly. The boot keeps the bottle from making noise when you set it down and it protects the bottom of the bottle. The rubber itself is pretty sturdy. It isn't going to bust if you drop your bottle. I would definitely recommend buying this product.

Must Have Accessory
I would recommend buying with 32 oz bottle. It helps with keeping the product from sliding around on smooth surfaces.

Cheap yet effective - what more can you ask for?
So glad Hydro Flask makes these! It’s like having a protective case for your expensive phone. I got a special edition 40oz raspberry/lava bottle on my recent trip to Hawaii and the cobalt medium flex boot fits perfectly and adds a nice contrast. I use this bottle a lot at work and before I got the flex boot I would always have to gently place my bottle on a coaster or paper towel to make sure it doesn’t get scratched/dented. Now I can finally place it down normally - thank you Hydro Flask!

Definitely worth it!!
I just got this for Christmas to go along with my hydro flask, it works great to keep the bottom of the bottle protected and to keep it dent free. Not only does it add protection, but it adds style too!

Love it
I bought the flex boots to add on as a first and I love them. It protects the bottom from damage and it quiets the sound of the bottle hitting the table when put down. Also looks very sleek.

Saved My Water Bottles Life
I bought this with my 40 oz White hydro-flask. I bought the black boot so it adds really good contrast to the white bottle. I have dropped this many times with it all the way full and it doesn't DENT! I was very impressed. Another great thing about the boot is that it's a cheap accessory for your hydro-flask. But before when I would set down my hydro flask it would make a loud noise but now with the boot it basically makes no noise.

Questions
which boot fits the 16oz tumbler?
The Small Bottle Boot fits all 12-24 oz wide & standard mouth flasks. So this one will fit the 16 oz Tumbler.
The Medium Bottle Boot fits the 32 & 40 oz wide mouth flasks; besides the 32 oz Trail Series.
Date published: 2020-04-26
will this fit the new "32 oz Lightweight Wide Mouth Trail Series" bottle?
Unfortunately, we do not currently have a bottle boot to fit this size and style bottle.
Date published: 2020-07-05
I really like the new color, fog. Would a stone color flex boot look good with this, or should I just go with black. I am thinking stone because I like more lighter colors, but not too bright. Thank you!
The Fog color is a very pale purple/blue color; almost like a periwinkle color. Yes, Stone or Black would look good with it. If you purchase either one and find that the color does not work for you, you are able to return the item within 30 days of receipt for a refund; as long as items are unused and in their original packaging.

Has the medium boot been updated to reflect the newly-redesigned (as of early Jan 2020), more rounded shape of the base of the 32oz wide-mouth flask?
We are not redesigning the boots because they will still fit the new bottles.
Date published: 2020-06-24

I was thinking about getting a hyrdroflask in the color, Frost. Since it is a light color, will getting a boot discolor or ruin the color of the bottle?
No, it should not discolor the bottle.

What color would look the best on the lemon 32 oz?
Personally, I like the black boot on the Lemon flask. But it is a personal choice.
Date published: 2018-07-18
Does the flamingo straw lid match the hue of the flamingo boot?
They are a little off. The materials used to make the caps and the boots are different, so the colors are off a little. The boot is a little darker than the cap.
Date published: 2019-01-24
Would this boot fit a 40 oz hydro?
Yes, the medium boot is for the 40 oz flask.
Date published: 2019-05-10
does it fit on the 12 oz food flask?
No. The food flasks are not really meant to have the boots. The base of the food flask is a little different than our other bottles.
Date published: 2018-02-05
Does the boot have the "Hydro Flask" on it?
The boot does say Hydro Flask.
Date published: 2018-05-14
Does it fit the 32 oz growler?
Yes! Funny story though, the 32oz growler is about .2 centimeters less in diameter than a wide mouth 32oz flask. The boot will fit but it could feel slightly lose but not lose enough to fall off or anything.
Date published: 2019-09-01
Which boot fits the 20 oz wide mouth? (It’s one of the coffee ones with a flip lid)
The small boot would be the one to fit.
Date published: 2018-09-30
I havea raspberry colored 32 ounce bottle. what color boot would look good
That would be a personal preference. Personally, I think any of them except the Flamingo would look good.
