FAQs

How do I know what SlipFin Pro size I am? Sizing is based on foot width and fullness — not shoe size. Use a soft tape measure (in cm), wrap it around the top of your foot just in front of your ankle, all the way around and back to the starting point. Find that measurement on the size chart and select that size.

What if I'm between sizes? Choose the smaller size for a snugger, performance-oriented fit. Choose the larger size for a more relaxed, comfortable fit. Narrow feet: choose smaller. Wide feet: choose larger.

Should SlipFin Pro fit tightly? Yes. SlipFin Pro is designed to fit securely. A snug fit keeps the fin in place during swimming while still allowing natural ankle movement.

How far up my foot should it go? Does it cover my heel? SlipFin Pro should cover approximately ½–¾ of your foot. It is not intended to go over the heel.

How do I get SlipFin Pro on? Wet your foot and the fin, then pull it on by the sides. It goes on most easily in the water.

How do I get SlipFin Pro to stay on? Once the fin is on, squeeze the air or water out of the toe area by pulling the front of the fin back toward you. This creates suction and keeps the fin in place. If it's not holding, there is likely too much air or water still inside.

There's extra space at my toes — is that normal? Yes, this is by design. Your toes should not touch the front of the fin. That extra space is what creates the suction that holds the fin securely in place.

Can I do flip turns and push off the wall? Yes. SlipFin Pro is designed for swimming, flip turns, and push-offs when properly fitted. Plant your feet firmly on the wall before pushing off. Because the heel and ankle are free, turns may feel different from traditional fins until you get accustomed to the fit.

How do I remove SlipFin Pro? Peel the edge of the fin away from your foot to release the suction, then slide the fin off.

What if the sock portion becomes deformed? Gently fill the sock portion with a pair of socks or another soft item and leave overnight. This helps the fin return to its original shape.

Can SlipFin Pro be used for all four strokes? Yes — freestyle, backstroke, breaststroke, and butterfly. The strapless design allows natural ankle movement, making it a versatile training tool for improving kick technique, body position, and water feel across all four strokes.
