General Information

What are Slappa’s Thongs Made of?

Slappa’s Thongs are made of a foam called EVA or Ethylene Vinyl Acetate.

How are they made?

Slappa’s are made using a process called ‘Closed Cell Foam Injection’. During this process, EVA foam is injected into closed cell moulds. This means that each thong is a single solid piece with no plug to pull out or seams to rub your foot wrong. It is also what gives every pair of Slappa’s Thongs its own unique and individual look.

Where are Slappa’s Made?

Slappa’s Thongs are made in China due to the lack of availability of manufacturers in Australia capable of closed cell foam injection. Slappa’s Thongs are committed to ensuring that all our thongs are made to high standards and meet all Australian requirements. We visit our manufacturers on a regular basis to ensure quality standards of production and human rights are being met.

Are Slappa’s Thongs orthotics?

While Slappa’s are not an approved orthotic, many clients have taken their Slappa’s Thongs to their podiatrists for review and have been told they are happy for them to wear Slappa’s. We even have some podiatrists who stock Slappa’s and know of many physios who recommend them to their clients.

Is Slappa’s an Australian company?

Yes! Slappa’s are proudly owned and operated in Australia with our headquarters in Darwin.

Why are they called Slappa’s Thongs?

When founder Denise was first rolling the product out, she asked all her family and friends to come up with and vote on the name the thongs were to be called. Slappa’s Thongs was the winner! The name has stuck and the thongs have been known as ‘Slappa’s’ ever since.

Why Should I Buy Slappa’s Thongs

Top reasons to buy Slappa’s Thongs

Here are just some of the reasons we hear from our happy customers why they love their Slappa’s

  • Super comfy
  • Great for those who suffer from Plantar Fasciitis
  • Work well for people who require orthotic footwear or orthotic friendly shoes
  • Great arch support
  • Moulds to your foot shape
  • They don’t make your feet get smelly
  • They don’t have seams that rub and give you blisters
  • You can walk for miles in them
  • Relaxes sore and tired feet
  • Protects your posture
  • Good life span
  • Great selection of colours
  • Extremely lightweight and durable

Why are Slappa’s Thongs so comfortable?

Slappa’s are super comfortable because they are made out of a foam, better known as EVA. EVA is a soft but durable material which allows your foot shape to mould into the thong, making them very comfortable to wear. Slappa’s Thongs also have great arch support which also contributes to the comfort. Slappa’s Thongs are made firm, however as you mould into them they will soften and mould to your foot shape. The straps will loosen and the thongs will give a little in length. So it is recommended you fit your Slappa’s firm to allow for this and then they will be a perfect fit and give you the best comfort, fit and support.

Do they make your feet sweat?

I personally don’t have a problem with my feet sweating, however if you do have a problem with sweaty feet I won’t say no. Sweat is caused mainly from feet or shoes being dirty. Slappa’s are easy to clean. Scrub with just about anything, wear in the shower or put in a cold water washing machine.

Looking after Slappa’s Thongs

Can Slappa’s Thongs shrink?

Yes, they can. Do not leave your Slappa’s Thongs in a hot car, closed hot tent or in direct sunlight for long periods of time.

What should I do if my Slappa’s Thongs get stuck in mud or sand?

It is best to take your foot out of the thongs and then pull the thong out with your hands from the sole, not the toe piece. This is so you don’t weaken or put pressure on the toe piece.

How durable are Slappa’s Thongs?

EVA is a very durable and flexible material which makes Slappa’s Thongs quite strong and long-lasting.

What shouldn’t you do with your Slappa’s Thongs?

  • Go rock climbing or walk on very jagged materials
  • Leave them in a hot car, tent or in direct sunlight for long periods
