All feet are different, so fitting a foot into a fixed shape foot cavity of moulded flexible material is an inexact science. That makes it very hard for us to tell you exactly what size you will need without you trying it on.
We have tried to give you enough information to guide you to make an informed decision on the best size for your feet.
Our fin sizes are pretty close to shoe sizes but our different models have slight variations in their unique foot cavity – universal, or specific left & right.
Rule 1: Check Length - Measure heal-to-toe of your foot to see that it would fit into the foot cavity.
Rule 2: Check your regular shoe size, e.g., US Mens, US Womens, and Euro to see if it is close to your shoe size.
Rule 3: Ask yourself if you like your fins to fit snug, or not. Allow +/- 3-5mm in length for your ideal comfort.
TIP: If you’re still not sure, then order 2 pairs and then return the pair that doesn’t fit, for a refund on the cost of the returned item.
Please view our sizechart to ensure you get the right fit.
