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.

Trail performance. Barefoot mechanics. Finally together.
Active Boots Sports puts an athletic trail silhouette on a true anatomical last. Wide toe box for full toe engagement on every surface. Zero-drop sole for natural weight distribution through every stride. Thin flexible outsole so your foot can actually feel — and respond to — the ground beneath it.
What your current sports boot is doing to you
Every cushioned, heeled sports boot is doing the work your foot should be doing. Over time: arches weaken, proprioception drops, your knees absorb forces your foot should be handling. The more support your shoe provides, the less your foot provides for itself.
What Boots Sports does instead
- Athletic trail silhouette — performance without the biological cost
- Wide anatomical toe box — toes engage and splay on every surface
- Zero-drop flat sole — correct weight distribution for trail and training
- Thin flexible outsole — 26 bones and 33 joints finally moving freely
Perfect for
Trail walking · Sports & training · Outdoor activities · Active barefoot lifestyle
Sole durability
Active Boots Sports uses a trail-rated rubber compound with multi-directional lug geometry — designed for surfaces that eat through standard outsoles fast. The compound is chosen for grip-to-durability ratio: soft enough to grip technical terrain, hard enough to resist premature wear. Under mixed trail/urban use: 700–1,100 km. The zero-drop construction distributes load evenly across the entire outsole, preventing the heel-heavy wear pattern that shortens most hiking boots' lifespan.
Care note: rinse mud off immediately after trail use. Dry naturally — avoid direct heat. Inspect lugs every 200 km.
