– Traditional swim fins can feel bulky, heavy, and restrictive. FINIS SlipFin Pro is designed to give swimmers the power of a fin with a lighter, more natural feel that supports good technique and race-pace rhythm.

– FINIS SlipFin Pro slips over the front half of the foot while leaving your ankle and heel completely free. Its patented design creates a gentle seal that holds the fin in place – with no straps and no heel cup – delivering comfort, flexibility, and power.

No matter how you swim, SlipFin Pro helps you feel more connected to the water.

FEATURES & BENEFITS

– EXCLUSIVE STRAPLESS & HEEL-FREE DESIGN

Fits snugly over the front half of the foot, leaving the heel and ankle completely free. Eliminates heel rubbing, blisters, and Achilles tendon strain during long training sessions.

– PATENTED NATURAL SEAL

Made from soft, premium flexible silicone that automatically contours to your instep, holding the fin securely in place under water pressure without needing straps or heel cups.

– FULL ANKLE MOBILITY

Allows 100% natural ankle movement, helping swimmers feel the water better and maximize kicking efficiency.

– MAINTAIN RACE-PACE RHYTHM

Ultralight construction combined with balanced resistance ensures your kick tempo stays synced with your arm stroke—preventing timing disruptions and premature fatigue.

HOW TO PUT ON YOUR FINS (DIP – SLIP – SQUEEZE – SWIM)

To ensure a snug fit and prevent slipping while swimming, follow the simple 4-step rule:

– Dip: Wet both your feet and the fins before slipping them on.

– Slip: Slide the front half of your foot into the foot pocket.

– Squeeze: Gently press the flexible shell so it hugs your instep smoothly.

– Swim: Jump in the pool and enjoy a smooth, natural kick cycle.

SIZE GUIDE

Unlike traditional swim fins sized by shoe size, the FINIS SlipFin Pro is measured by Instep Circumference (wrapped around the top of your foot, just in front of your ankle) to ensure a precise vacuum fit:

– Size S (Small): Instep Circumference from 21.0 cm – 24.5 cm

– Size M (Medium): Instep Circumference from 23.5 cm – 27.0 cm

– Size L (Large): Instep Circumference from 26.0 cm – 28.0+ cm

Fit Tip: If you fall between sizes, size down for a snug, high-performance fit (Performance Fit), or size up for a more relaxed, comfortable daily training fit (Relaxed Fit).

CARE INSTRUCTIONS

– Rinse with fresh water: Rinse thoroughly with clean tap water after every swim to remove residual chlorine or saltwater.

– Air dry naturally: Allow to dry in a cool, shaded place away from direct sunlight or high heat.

– Avoid heavy crushing: Do not place heavy equipment on top of the fins inside your swim bag to preserve their natural molded shape.
