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.

Women's shoes have been designed for display for too long. U Woman was designed for feet.
Most women's shoes are shrunken men's shoes — which were already badly designed. U Woman starts with a different question: what does a healthy woman's foot actually look like? The answer shaped everything — a wider toe box matched to women's natural toe splay, a zero-drop sole aligned to women's natural posture, a flexible outsole that moves with a woman's natural stride.
Why women's feet suffer more
Women are four times more likely than men to develop bunions, plantar fasciitis and toe deformities. The cause isn't anatomy — it's shoes. Pointed toe boxes designed for fashion, elevated heels designed for aesthetics, rigid soles designed for durability. All wrong for feet. U Woman corrects all three.
What U Woman does instead
- Women's anatomical last — wider, shaped for actual women's feet
- Wide toe box — natural splay, zero bunion pressure
- Zero-drop flat sole — natural alignment, reduced knee and back strain
- Flexible outsole — elegant, unrestricted movement
Perfect for
Everyday wear · Office · Weekend walks · Travel · Any occasion
Sole durability
The U Woman outsole uses the same high-abrasion rubber compound as Calyon One, calibrated for the lighter average load of a women's last. Consistent 4mm thickness across the full footbed. Under daily wear: 800–1,200 km — the flat zero-drop geometry ensures even distribution, so the sole wears uniformly rather than eroding at a single pressure point. The women's sizing runs narrower at the heel, which actually reduces torque on the sole seam and extends adhesive bond life.
Care note: wipe with a damp cloth. Air dry naturally. Avoid direct heat — rubber compounds harden and crack if stored near radiators.
