Geox size guide: how to find your perfect fit when buying online
Ordering Geox shoes online and unsure whether to size up or stick with your usual number? You're not alone. Geox uses Italian sizing conventions, and their lasts tend to run slightly narrower than many shoppers expect — especially when ordering from retailers that ship to Cyprus without the option to try before you buy. This Geox size guide covers the official conversion charts, width notes, kids' growth allowances, and a step-by-step foot measurement method so you can order confidently from any of the retailers available on Geox.
Why Geox sizing matters (Italian sizing conventions)
Geox is an Italian brand, and like most Italian shoemakers, it uses EU sizing as its primary reference system. However, "EU 42" doesn't mean the same thing across every brand. Italian lasts — the moulds around which shoes are built — tend to be narrower and slightly shorter in internal length than their Northern European or American equivalents at the same EU number.
In practice this means: if you normally wear a comfortable EU 42 in Nike or Adidas, you may find the same size in Geox feels tighter across the forefoot, particularly in leather dress shoes and loafers. Sneaker models with knitted or mesh uppers are more forgiving, but the sizing on the box still follows the same Italian conversion table.
This is why measurement-based sizing is essential when buying Geox online — and why we see "sizing" as one of the most common reasons for returns across the retailers that ship to Cyprus and that we track on Stylino.

Width considerations and last shapes
Geox does not offer multiple width fittings (like "D", "E", or "wide") in the way that some American brands do. However, the internal width varies significantly depending on the shoe's last:
- Dress shoes and loafers (e.g. the Symbol or Hampstead line): these use a narrow, tapered last. Independent fit reviews consistently note that these styles run about half a size small in effective length and narrower across the ball of the foot.
- Sneakers and casual styles (e.g. Nebula, Aerantis): these use a rounder, more athletic last. Standard EU sizing is generally accurate here.
- Sandals and open-toe styles: these tend to be true to size since the open construction is more forgiving on width.
Practical advice: if you have wider-than-average feet (E width or above) and are ordering a Geox leather shoe, consider going up half a size. For their sneaker and knit models, your regular EU size should work.
Special considerations for kids (growth allowance)
Children's feet grow rapidly — on average 1–2 mm per month between ages 2 and 6 — so sizing requires a different approach than adult shoes.
Growth allowance rule: when measuring a child's foot for Geox shoes, add 10–12 mm to the measured length before checking the chart. This gives roughly a thumb's-width of space at the front, allowing 2–3 months of growth before the shoe becomes too tight.
Geox-specific notes for kids:
- Geox kids' shoes (especially the "Junior" and "Android" lines) have reinforced toe caps. The internal length is slightly shorter than the outsole measurement because of this reinforcement — trust the foot-length column in the chart above rather than measuring the sole externally.
- Velcro-strap models are more forgiving on fit than lace-ups because the closure can adjust to swelling throughout the day.
- If your child is between sizes, always size up — a slightly loose shoe with an insole is better than a tight one that will need replacing in weeks.
How to measure your foot at home
Getting an accurate foot measurement is the single best way to avoid returns when ordering Geox online. Here's the method we recommend:
Step 1: Gather your materials
You need a piece of blank A4 paper, a pen or pencil, a ruler or tape measure (in cm), and a hard, flat surface (tile or hardwood — not carpet). Measure in the afternoon or evening when feet are at their largest after a day of walking.
Step 2: Tape the paper and stand on it
Tape the paper to the floor so it doesn't slide. Stand on it with your full body weight, wearing the type of sock you'd normally wear with the shoes you're buying. Place your heel against a wall or a heavy book for a fixed reference line.
Step 3: Mark your longest toe
With the pen held vertically, mark the tip of your longest toe (this isn't always the big toe — for some people it's the second toe). Don't angle the pen inward; keep it perpendicular to the paper.
Step 4: Measure the distance
Remove your foot and measure from the edge of the paper (where your heel was against the wall) to the pen mark. Record in centimetres to one decimal place. Repeat with the other foot — your feet are rarely identical.
Step 5: Use the larger measurement
Take the longer of the two measurements. This is your foot length. Find it in the "Foot length (cm)" column of the Geox size chart above. If your measurement falls between two sizes, choose the larger size — especially for leather or structured styles that won't stretch much.
Common return reasons and how to avoid them
Based on the patterns we observe across the retailers that ship Geox to Cyprus and that we track on Stylino, the most frequent return reasons for Geox footwear are:
Too narrow across the ball of the foot — almost always in the dress shoe and loafer category. Avoid by: sizing up half a size in structured leather styles or choosing their sneaker-last alternatives.
Length fine but heel slips — this happens when shoppers size up for width. Geox's narrow heel cup means the back doesn't grip when the forefoot area has been given extra room. Avoid by: looking for lace-up or strap-closure styles if you need to go up.
Kids outgrow them before the season ends — parents buy for the current measurement without growth allowance. Avoid by: adding 10–12 mm to the measured length as described in the kids section above.
Assuming running-shoe sizing applies — Geox EU sizes don't align 1:1 with athletic brand sizing. An EU 42 in Geox may feel like an EU 41.5 in Nike. Avoid by: always using the cm-based measurement rather than converting from another brand's size.

FAQ
Do Geox shoes run small?
Not exactly — but they run narrow. In terms of length, Geox follows standard Italian EU sizing. However, their leather and dress shoe lasts are narrower than many shoppers expect, which creates the sensation of the shoe being "small." If you measure your foot and match it to the cm column in their chart, the length will be correct. The issue for most people is width, not length.
Should I size up in Geox?
For sneakers and casual styles: usually no — your standard EU size should work. For leather dress shoes, loafers, and pumps: going up half a size is a common and reasonable precaution, especially if your feet are average-to-wide. Always base the decision on a cm measurement rather than guessing.
Are Geox kids' sizes the same as other EU kids' shoes?
Geox kids' shoes follow standard EU sizing in terms of the number on the box, but the internal fit can be slightly snugger due to their reinforced toe boxes and Respira membrane construction. The safest approach is to measure the child's foot length and add 10–12 mm for growth, then match to the chart.
How do Geox sizes compare to Nike or Adidas?
Geox uses Italian EU sizing, which tends to be about half a size smaller in felt length compared to athletic brands at the same EU number. If you're an EU 43 in Nike, you may need an EU 43.5 or even EU 44 in a Geox loafer — but in a Geox sneaker, EU 43 should be fine. The foot-length measurement in cm removes this guesswork entirely.
