Size Guide
EQUINOX shoes are sized in EU. Use the guide below to find your perfect fit.
How to Measure Your Foot
- Place a piece of paper on a hard floor (not carpet — carpet compresses under your foot and gives a false reading).
- Stand on the paper with your full weight. Your foot spreads under load, so always measure standing, not sitting.
- Mark the back of your heel where it touches the paper.
- Mark the tip of your longest toe. This may be your second toe, not your big toe — check both.
- Measure the distance in centimetres between the two marks.
- If your feet differ in size (very common), use the measurement of the larger foot.
- Add 0.5–1 cm for toe clearance. This is your target internal shoe length.

When In Doubt, Size Up
If your foot measurement puts you between two sizes, always choose the larger size. In a wide-toe-box barefoot shoe, a slightly longer fit is better than a slightly shorter one — your toes need room to splay and spread naturally. A shoe that is 0.5 cm too long is comfortable. A shoe that is 0.5 cm too short is not.
Width
EQUINOX shoes are built on an anatomical last — they are wider than conventional shoes by design. If you have particularly wide feet, you will likely find this more comfortable than any conventional shoe you have worn. If your feet have been compressed by narrow shoes for years, your toes may need a few weeks to decompress and spread into the available space. This is normal and expected.
Five-Toe Models (Aqua Five and Trail Aqua)
The Aqua Five and Trail Aqua have five individual toe pockets. Sizing works the same way — measure your foot length and match to the chart above. The toe pockets are designed to accommodate the natural range of toe lengths. If you have unusually long second or third toes, size up one.

Shipping & Returns
Shipping & Returns
Every other water shoe puts all five toes in the same pocket. EQUINOX Aqua Five gives each one its own space — because that's how your foot was actually designed to work.
Five individual toe pockets follow the exact shape of your foot, letting each toe grip, balance and react independently. Quick-dry mesh drains within seconds. A non-slip rubber sole grips wet rocks, boat decks and river beds. Zero-drop platform keeps your posture natural in and out of the water.
Why individual toe pockets change everything
When your toes are crammed together in a single pocket, they can't grip, splay or react to the surface beneath them. That's why most water shoes feel unstable on rocks and slippery on wet surfaces. Aqua Five separates each toe — restoring the natural grip mechanism your foot was built with.
Key features
- Five individual toe pockets — each toe moves independently
- Quick-dry mesh upper — drains and dries within minutes
- Non-slip rubber sole — grips wet rocks, boat decks, river beds
- Zero-drop platform — natural posture in and out of the water
- Unisex sizing — EU 36–45
Perfect for
Beach walks · River crossings · Kayaking · Boat trips · Pool days · Coastal hiking · Water parks
Sole durability
The Aqua Five outsole is a non-slip vulcanised rubber compound — the same category of material used in marine and water-sport footwear. The critical property here is wet-surface coefficient of friction, not dry-terrain abrasion resistance: the compound is formulated to grip wet rock, fibreglass boat decks and river beds where standard rubber slides. Under regular water use: 400–700 km. The five-toe sole architecture means wear is spread across more surface area than a standard flat sole, which actually extends useful life despite the softer compound.
Care note: rinse with fresh water after every saltwater or pool use. Chlorine and salt both degrade the rubber compound over time. Air dry completely before storage.

THE PROBLEM
Every other water shoe puts your toes in the same prison
Standard water shoes cram all five toes into one pocket. They can’t grip, splay or react to the surface beneath them.
THE SOLUTION
Five individual toe pockets — built the way your foot works
Aqua Five gives each toe its own space — so you grip, balance and move the way you were built to.
THE SCIENCE
Your toes are your body’s natural grip system
Each toe contains bones, joints and muscle connections that evolved to grip, sense and stabilise on varied surfaces.
THE TRANSFORMATION
Week by week, your body recalibrates
Days 1–7: Foot muscles activate. Balance improves.
Month 2+: 94% say they’ll never go back.
See the difference
Conventional water shoes block your toes. Aqua Five gives each one its own space.
