FAQ’s and Comments

Here are some frequently asked questions or comments we receive from our customers.


I had a blowout! WTF?!?! You said they wouldn’t break!
What should I do if the boomerang plug snaps off?

Now this is a disaster!!! But no, we do not claim that the bases or straps are indestructible. They are made from rubber and will wear out over time and can break. This is not meant to happen, but due to the nature of the material it can totally happen. The boomerang plugs have been designed to pull through instead of snapping off. Allowing you to push it back in if you get ‘un-plugged’.

It is unlikely to happen, but if it does, take a photo and send it to us straight away along with your color and size and we’ll send you a new pair of straps ABSOLUTELY FREE!! That’s our no blow out guarantee!



Why do the women’s only go to a size 10/11?

The thongs are UNISEX and there isn’t much difference in width once the thongs get up to a size 10/11 and beyond. Slim straps will fit the regular base up to a size 10/11 and vice versa (see below for the next question).
If you’re a beautiful lady who needs flip flops larger than a size 10/11, we recommend the regular 12. You can also purchase regular diamante’ straps to give them that “bling bling” look.


Can the slim straps fit the regular bases and vice versa?

They sure can!
All our thongs actually say ‘unisex’ on the heel. So don’t be embarrased if you’re not buying them from the ‘mens’ or ‘womens’ categories on the website.
Slim straps can be put in to the regular bases with the corresponding size straps.

Custom Fit:
If you have wide feet and find the straps are a little tight but the length is correct. You can always go up a size in the straps ONLY. Same goes for narrow feet. If they feel too loose… go the next size down in straps. This will obviously change the fitment so you might need to test them out. We’re more than happy to help with this when you order.



Is it OK to leave them in direct sunlight?

Prolonged exposure to extreme heat can cause them to shrink a little or warp the bases.
Best not to leave them in direct sunlight for a long period of time.


What do I do if my strap pulls through?

The beauty of our flip-flops is that the plugs have been designed to fit through the base at a certain angle. If the strap and base come apart with force, ideally the strap will pull through and not snap off. This way, it is fixable and you don’t have to walk around with one flip-flip on. Simply push the long arm of the boomerang plug through first and replace the strap in to the base. Walk on my friend… Walk on!


How do I use the printable sizing chart?

  1. Click on the link of your desired size on the sizing chart page or size chart tab of the individual product pages
  2. The PDF will open in a new window
  3. Click FILE then click PRINT
  4. Make sure PAGE SCALING is set to NONE
  5. Place your foot in the outline to see if that is your correct size

Although the bases may vary slightly, it is best to measure your foot or an old pair of flip flops from the center of the heel to the top of your big toe.

Please always check your size before ordering as you will incur postage fees should you need to swap for a different size.

The size range is based on the Men’s U.S. size range, although they are labelled unisex. This means that if you are ordering a ladies slim style and you are normally a 9, you will need to order a 7/8 instead. If you are normally a 7/8, you will need to order a 6 and so on… best to measure your foot with the sizing charts.


What happens if I order the wrong size?

You idiot!!! Naaahh… just jokes! This happens from time to time. Just keep them in mint condition and send them back to us at: Boomerangz LLC, 6280 Highlands Ct. Ponte Vedra Beach, FL 32082 USA. Please include a self-addressed pre-paid large envelope inside the satchel you send them back in (that’s 2 large envelopes). Also, it is a good idea to have ‘tracking’ on the package as it will be your responsibility until we receive them back.. Your other option is to give them to someone else as a gift… and get yourself another pair! This way you won’t be wasting money on postage costs.



What if I don’t like the color when I receive the product?

The product images on the website are accurate to the actual colors but they might vary depending on the resolution of your computer screen or phone settings. If you don’t like the color we can exchange them over for you. Send them back to us at: Boomerangz LLC, 6280 Highlands Ct. Ponte Vedra Beach, FL 32082 USA. Please include a self-addressed pre-paid large envelope inside the large envelope you send them back in (that’s 2 large envelopes). Also, it is a good idea to have tracking on the package as it will be your responsibility until we receive them back.


Will I get a blister?

Hmmmm… you might get a blister. I got a blister once from the strap rubbing on my foot in a different spot that my skin wasn’t used to. Stupid soft beautiful skin! I soon toughened up though and no more blisters! But it’s not the end of the world, we do recommend a band aid over the blister.


What is the meaning of life?

This is open to personal interpretation… Here at Boomerangz, we think life is for enjoying experiences and spending time with friends and family. You need to grow and evolve as a person and you will feel a strong sense of self-worth. Do what you love, whenever you can.



I’m a retailer and I want to sell your interchangeable bases and straps in my store – how do I go about this?

Get in touch with us via e-mail at: [email protected]
We will respond with some wholesale prices, point of sale information and make sure you’re a good fit to help get our flip flops out to customers all over America.


How long do the bases last?

This depends on weight, size, where you wear them, how often you wear them, pressure points, the way you walk and a bunch of other factors. While this shouldn’t happen too soon, it is a sign that you love wearing your flip flops! Due to the rubber material of our products they will suffer from wear and tear, from every footstep you take and being exposed to the elements. There is a fine line between having the rubber soft and comfortable (wears out quicker) or really hard (which lasts longer). We aim in between so they are soft, comfortable and mold to the shape of your foot. Often the bases will start off harder but will soften up soon after wearing them.
We put our product through rigorous testing to get the perfect combination of rubber bounce back and comfort. (That’s not a pair of ours below by the way…)


Is your product made in an ethical way?

Our manufacturing partner’s facility is a family owned and run operation. High standard workplace conditions and safety audits are a regular occurrence and they maintain good working conditions. There are no under-age workers and we go there several times a year for inspections of our manufacturing facilities. The product is made without any nasty additives (such as Azo-dye colors), all products are lead free and no animals are harmed in the making of our products.


Which retail stores can I find your cool, interchangeable and no blow-out flip flops in?

This is constantly changing as we are continually adding our product range to stores all over the world. Some stores will close down, some won’t hold our product over winter and we can’t guarantee they have all the styles, sizes and colors. If you would like to know if our product is stocked in a store near you, simply get in touch via the contact us page.
