Ordering shoes online becomes much less uncertain when the decision is based on measurements rather than the size printed on an old pair. This guide is intended for shoppers comparing casual shoes, sneakers or classic footwear without an in-store fitting. It explains how to measure both feet, interpret a model-specific chart and give the seller enough information to assess the likely fit. Different offers can be reviewed through the Mytrade.kz marketplace.
A familiar size number is only a starting point
A customer may regularly wear EU 39 and still need another size in a different model. The number on the box does not describe the complete internal shape of the shoe. Toe-box geometry, width, instep depth, heel construction, lining and insole thickness all affect how the same nominal size feels.
International standards also distinguish between sizing systems. ISO 9407 defines Mondopoint using measurements of the foot the footwear is intended to fit, while a separate ISO standard covers conversion among major systems. This is why an EU-to-UK or EU-to-US conversion should be treated as a reference rather than a precise fitting result.
The commercial impact of inaccurate online selection is substantial. The US National Retail Federation estimated that 19.3% of online sales would be returned in 2025, while 82% of surveyed consumers considered free returns important when shopping online. The figures cover retail generally, but they show why accurate product information matters before a footwear order. Information about the seller and its assortment is available on the PASSAGE company profile.
Build a reliable measurement rather than tracing loosely
The American Podiatric Medical Association advises shoppers to “measure both feet—late in the day—and shop for the larger foot.” Feet can differ in size, and the larger measurement should guide the order. Measuring later in the day also reflects the condition of the foot after normal standing and walking.
A seven-step home measurement method
- Place a sheet of paper on a hard, level floor with one edge against a wall.
- Wear the same type of socks you expect to use with the new shoes.
- Stand upright with the heel lightly touching the wall and your weight distributed naturally.
- Mark the position of the longest toe; for some people, this is the second toe rather than the big toe.
- Measure from the wall-side edge of the paper to the mark in millimetres.
- Measure the widest part of the forefoot without pulling the tape tightly around it.
- Repeat the process for the other foot and record the larger length and width.
Take the measurements twice. A difference of 2–3 mm between attempts may indicate that the foot moved, the heel separated from the wall or the marking tool was held at an angle. Once the figures are stable, compare them with the information supplied for a specific model in the current footwear offers from PASSAGE.
Create a short fit profile for the seller
A useful online fitting request contains more than “I usually wear size 40.” Prepare a compact profile with four details: the length of the larger foot, forefoot width, instep characteristics and the type of socks planned for the shoe.
For example: “My right foot is 253 mm long, my left foot is 256 mm, the larger foot is 98 mm wide, and I have a medium instep. I plan to wear the shoes with thin everyday socks.” This gives the seller a clearer basis for comparing your measurements with the shape of the model.
- A wide forefoot may require a rounded or more spacious toe box.
- A high instep may need adjustable laces, elastic sections or greater upper depth.
- A narrow heel requires attention to rear-foot hold rather than simply choosing a shorter shoe.
- Thick seasonal socks must be included during measurement if they will be worn regularly.
Product photographs are useful for seeing the toe shape, sole and upper material, but they do not show internal volume precisely. Additional visual information can be found in the footwear videos published by PASSAGE.
Identify what the size chart actually measures
Three different values may appear in an online product description: recommended foot length, removable-insole length and footwear size. They are not interchangeable. Foot length describes the customer. Insole length describes a component inside the shoe. The listed size is the manufacturer’s designation for the complete model.
Suppose the larger foot measures 255 mm. If a chart states that a particular size is intended for a 255 mm foot, the manufacturer may already have allowed the necessary internal space. Adding another centimetre before selecting the row could produce a pair that is too long. However, if the chart lists only the physical insole length, the same 255 mm value may leave insufficient room in front of the toes.
Before choosing a row, check the chart heading and ask whether the figure represents the foot or the insole. Model notes and updates from the seller can also be reviewed in the PASSAGE news and offers section.
Use toe clearance as one checkpoint, not the whole decision
Guidance from Guy’s and St Thomas’ NHS Foundation Trust states: “About 1cm space between the end of your longest toe and the end of your shoe is ideal.” This allows room for the foot to move forward during walking. It does not mean that every shopper should add exactly 10 mm to every measurement regardless of how the manufacturer prepared the chart.
A shoe can have enough space in front of the toes and still fit poorly. Excessive heel movement, pressure over the instep or compression at the widest part of the foot are separate fitting problems. Length should therefore be evaluated together with width, depth and heel retention.
Signs that length alone is misleading
- The toes have space in front but are pressed together from the sides.
- The foot slides forward because the heel is not held securely.
- The upper creates pressure or numbness over the instep.
- The shoe bends in a different place from the natural forefoot joint.
Videos of footwear in motion may help a buyer compare sole flexibility, upper construction and overall proportions. Broader visual comparisons are available in the short-video section on Mytrade.kz.
Ask five questions before completing the order
A precise question can prevent more uncertainty than choosing between two adjacent sizes without additional information. Send your measurements first, then ask about the characteristics of the exact model rather than the brand in general.
- Does the chart show recommended foot length or measured insole length?
- Does this model generally fit as labelled, or does its last run shorter, longer, narrower or wider?
- Is the toe box narrow, standard or spacious?
- Is the upper suitable for a high instep or a broad forefoot?
- What are the current fitting, exchange and return conditions for this order?
Do not assume that the conditions for one product automatically apply to another. Confirm them before payment and keep the measurements and model details in the order correspondence.
Run a ten-minute fit check after delivery
Try the pair indoors on a clean surface and wear the socks used during measurement. Put on both shoes, stand fully upright and walk for several minutes. Check each foot separately because the larger foot may reveal pressure while the smaller foot may reveal heel movement.
- The longest toe should not touch the front while standing or walking.
- The forefoot should not be compressed at its widest point.
- The instep should remain comfortable after fastening the shoe.
- The heel should be held without severe rubbing or repeated lifting.
- The toes should be able to move without gripping the insole.
Some upper materials may become softer with use, but a shoe that is too short will not gain the missing internal length. Pain, burning, numbness or toes striking the front should not be treated as a normal breaking-in stage.
A measurement-led order is easier to evaluate
The dependable sequence is simple: measure both feet, use the larger values, record width and instep information, establish what the chart measures and verify the last of the chosen model with the seller. PASSAGE in Esik offers footwear, apparel and accessories, including casual, classic and sports-oriented models. Providing measurements before ordering makes the discussion more specific to the selected pair.
When the numerical size appears correct but the feet still become tired, the cause may involve the shape of the last, heel control, toe-box width or the intended use of the shoe. These factors are examined in the previous article, why feet become tired even in new shoes: seven selection mistakes.
