Willi Footwear

About Us


Here at Boomerangz LLC, we provide our customers with a unique range flip flops. Our parent company, Willi Footwear has given this Aussie icon a stylish overhaul, focusing on ‘No More Blow-outs’ and ‘Interchangeable Bases & Straps’

You will find that there are many types of flip flops on the market, yet the only difference in the majority of these products is that the brand name has been carelessly slapped on an already existing standard product. This is known as a ‘me too’ product; when a company or brand want a share in that particular market but really have nothing special to offer the customer.

We are not a company that simply produce ‘me too’ flip flops… We are the footwear experts that have produced the ‘next evolution in flip flops’.



Way back before we even started the business, I was travelling around Europe for the Soccer World Cup. My friends and I had been dying to go to one of the beer halls in Germany only to suffer from “the dreaded flip-flop blow-out” (when the plug snaps off the strap) within a few feet from the front entrance where I wasn’t allowed in because wearing only one flip flip wasn’t considered appropriate footwear!

My friend and I sat in front of the beer hall for a while trying some MacGyver like solutions to fix my problem, including trying to put the strap back together with a paperclip, we borrowed a cigarette lighter off a random person and tried melting the rubber together… all to no avail… My friend ended up going in and borrowed one of our other friend’s flip flops to smuggle out so I could wear them in!

A year or so later, I met my soon to be business partner who was telling me of a similar experience he had where in the space of two steps, both of his flip flops had blown out, causing him to trip over and leaving him stranded, barefoot and needing to buy a new pair.
We got together, discovered that a lot of the flip flops on the market were all the same and decided they could use some improvement. We then started our business to solve this common problem.




The ‘boomerang’ shaped plugs have a larger surface area than the usual round plugs and keep the straps firmly in place. As every flip flop wearer knows, there is always a chance of the dreaded ‘blow out’ occurring and always at the most inconvenient times. The boomerang plugs are designed to fit through the hole in the base but only at a certain angle. If someone accidentally steps on the heel of your base for example, the plugs are designed to pull through the hole instead of snapping off completely, causing a ‘blow out’ while you hop around wearing one thong. Instead, you can push the plug back through the hole and be on your way. Of course, we don’t claim that our straps are indestructible and due to the nature of the material, the plugs can snap off. This is why it’s a good idea to have a spare set of straps at home, in your hand-bag, in your car… wherever you can easily access them, so you don’t have to worry about suffering a “blow-out”!

Change your flip flop straps and flip flop base combination yourself, as often as you like in less than 30 seconds with no tools and no fuss!

No more blow outs… just fashionable and comfortable footwear designed by you, to suit your lifestyle.

The interchangeable footwear comes in a unisex size range and consists of two styles: Regular – for those people with ‘normal’ feet, and Slim – mainly for ladies with ‘narrow’ feet. Regular and slim straps can be mixed with both regular and slim bases of the corresponding size so you really can create your own!

The sizing range is unisex and is based on the US men’s size. It ranges from 4/5 in the slim up to 13/14 in the regular. Some sizes are merged as there is an insignificant length between the two measurements.

Mix and match your bases and straps whenever you like!



We launched our new interchangeable range through crowd funding site Basically, for a product such as ours, it is like pre-ordering; if people don’t want your product – they won’t order it – simple as that! We thought it would be a great way to test the viability of our product and genuinely test the market by finding out if people wanted to make a purchase.

We managed to sell $10,000 worth of product in the FIRST HOUR, $15,000 a few DAYS later, $25,000 after just one WEEK and finished the campaign with just under $40,000 in sales!

During this short period of time we also managed to gain world-wide media exposure with several news articles published, including Australia’s largest financial publication – ‘The Financial Review’ and we also appeared on the front page of the ‘Gold Coast Bulletin’.

Some of the media logos are shown below which includes: International coverage from popular US website – (the article was shared over 1.6 thousand times), The Daily Mail UK, Yahoo Finance and Australian national radio stations such as Nova and Triple M as well as plenty of business and fashion news and magazines.
