Slips on. Stays put.

No straps. No heel.
Just a natural extension of your foot.

Traditional fins are bulky.
Restrictive. Heavy.

SlipFin Pro is not.

“It doesn’t change the way I
kick. It enhances how I
naturally kick.”

Meg Harris | 3x Olympic Medalist

“I can move my ankle fully
without pain. Other fins still
hurt when I kick. These don’t.”

Early Tester (Masters Swimmer)

“Big fins usually throw off my
timing. With these, my kick
stayed in sync with my arms.”

Early Tester (College Athlete)

DIP. SLIP.
SQUEEZE. SWIM.

The soft, flexible material creates a gentle
seal, holding the fin in place without straps.

Sizing is based on instep measurement, not shoe size.

Videos

Measure the circumference of your instep:

Wrap a soft tape measure around the top of your foot, just in front of your ankle.
Keep the tape flat and snug.
Use this measurement to find your size in the chart below.

No tape measure?

Use a shoelace or string, then measure it
against a ruler.

SlipFin Pro Size	Instep Circumference (cm)	Foot Width
Small (S)	21 - 24.5 cm	Narrow
Medium (M)	23.5 - 27 cm	Regular
Large (L)	26 - 28+ cm	Wide

Fit Tip: If you fall between sizes:

For a snug, performance fit → choose the smaller size.
For a more relaxed, comfort fit → choose the larger size.
Narrow toe box → choose the smaller size.
Wide toe box → choose the larger size.
