There's no doubt that '90s shoe trends are having a moment.

If you don't already own a pair of Adidas Sambas, chances are you've got Birkenstocks, Havaianas or Mary Janes sitting in your wardrobe.

Now, it's time to make room for another '90s favourite — one your ankles, lower back and knees will thank you for.

Enter: kitten heel thongs.

Watch: Leigh Campbell explains 'the Wrong Shoe theory'. Post continues below.

Since they're essentially thongs with tiny heels attached, they're comfortable and breathable for all-day wear, making them perfect for most occasions.

As a short girlie who is prone to blisters, I can confirm they're the perfect shoes to give me a little boost in height without causing any pain.

One of the most popular pairs of kitten heel flip-flops doing the rounds online (thanks to '90s fashion queen Hailey Bieber) is from Stockholm brand Toteme.  Here's what they look like.

Here is the red suede version of them.

They're super classy and chic, right? 

However… a pair of Totemes will set you back anywhere from $571 (for the iconic black) to $700 (for the red suede pair) on Farfetch.

So, we scoured the internet for the best affordable alternatives that are all under $100.
