Archies Flip Flops 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.
It is important to note, that it is not a concern if some of the back edge of the heel hangs over the edge of the flip flop (as per the below image).
If your heel is completely over the edge of the heel cup and squashing down on the rim of the flip flop, then the size is too small for you. However, some heel overhang is ok.
The most important thing is that the flip flops are comfortable and the arch support is in the correct position.
Sometimes it can seem that the fit is too small when it is actually perfect. In this case, it’s most likely that the tight strap and toe pole that’s stopping you from getting your foot all the way into the flip flop. To fix this, simply stretch the strap with your hands.

About the width
We find that most people, even those with wider feet can fit into our flip flops without issue, once they adjust the straps to suit their foot. If you have a particularly wide foot, we recommend choosing one size up.
