If you have average feet, Archies Thongs should fit you perfectly. Our thongs are designed with a ‘snug/tight’ fit in mind. They should “fit like a glove” with very little space in front of your toes and behind your heels. This will ensure that the arch support is in the correct position on the foot.
Here's a quick video on the perfect fit! (please note, the site on the video is our USA site, so it will be slightly different from our AU site.)
If you need any assistance in finding the correct size or fit, feel free to contact customer support.
