How do I measure my foot length and width at home correctly?

Stand with your heel against a wall, trace your foot on plain paper while bearing weight, mark the longest toe and heel and measure the straight-line length and widest forefoot point, then round up to the nearest 5 mm before comparing to a brand size chart.

One of my feet is larger-which size should I choose when buying sneakers?

Prioritise the longer foot and pick the size that fits it; when in doubt choose the larger size and use insoles or heel wedges to fine-tune the fit if needed.

What simple adjustments can I make if my new sneakers are slightly too long or slightly too tight?

For shoes that are slightly long try a thicker insole or a heel wedge, and for slight tightness consider stretching leather or canvas at a cobbler, wearing thicker socks briefly during break-in, or using lacing tricks for knit uppers.

How can I test sneaker fit quickly in-store or when I receive an online order?

With the shoe laced as you’d wear it, check for a thumb-width of space behind the heel, ensure you can wiggle your toes in the toe-box, and walk or jog briefly to detect rubbing or slippage; when buying online choose retailers with a simple returns window and use the size guidance on our product pages.

Measure standing, not seated

Weighing your foot ensures a realistic length and width measurement.

Why fit matters for men’s sneakers

A sneaker that looks good but pinches, slips, or makes your foot ache won’t get worn. We focus on long-term comfort: the right length, width and feel keep you moving-on the commute, at weekends, and when you’re on your feet all day. This guide is hands-on: simple measurements, quick at-home checks, and fit adjustments you can make with what you have.

Before you measure: when to re-check

Feet change with age, activity and seasons. Re-measure if you’ve bought new orthotics, started a training plan, gained or lost weight, or if it’s been more than 18 months since your last check. Always measure both feet-most people have one foot slightly larger.

Tools you’ll need

Sheet of plain paper, a pencil and a ruler
Socks you’ll normally wear with the sneakers (thin or thick)
Flat floor and a wall for a stable tracing

How to measure length and width at home

Follow these steps standing, not seated-your foot spreads under weight and that extra size matters.

Step 1 - Trace your foot

Place the paper against a wall, heel touching the wall. Stand with your foot flat, weight evenly distributed. Trace around your foot with the pencil held vertically. Repeat for the other foot.

Step 2 - Measure length and width

Mark the longest toe and the back of the heel, then use the ruler to measure the straight-line length in millimetres or centimetres. For width, measure the widest part across the forefoot outline. Round measurements up to the nearest 5 mm-this avoids a too-tight fit.

Step 3 - Convert to standard sizes

Brands differ, so use the measurements to compare to the brand’s own size chart where possible. If you don’t have a brand chart, use a trusted marketplace size chart as a starting point and prioritise the longer foot when choosing a size. When in doubt, choose the larger size and use insole/heel adjustments if needed.

Quick in-store and at-home fit tests

These simple checks tell you how a pair really performs once you’re moving.

The thumb test

With the shoe laced how you’d wear it, slide your thumb behind the heel: there should be a thumb-width of space. Less means tight at the heel; more means the shoe may slip.

Toe-box wiggle

You should be able to wiggle your toes freely. If toes feel squashed or the top feels pinched, look for a model with a wider last or a roomier toe-box.

Walk and jog test

Walk briskly and, if possible, jog lightly for a minute. Pay attention to rubbing, hot spots or slipping. Try these movements on the surface you’ll use the shoes most on (pavement, treadmill, gym floor).

If you’re buying online, compare the retailer’s return window and choose a site that makes returns simple-this removes the risk of trying a new brand size. We list size guidance on product pages, and you can browse our Men sneakers for common-fit models.

How to adjust fit without buying a new pair

Small fit issues are normal and often fixable with inexpensive adjustments.

If the shoe is slightly long

Use a thicker insole or a heel wedge. A cushioned insole gives lift and fills dead space; heel wedges stop slipping without changing toe length.

If the shoe is slightly tight

Stretching leather or canvas at a reputable cobbler is an option, or try wearing thicker socks with heat for a short break-in. For knit uppers, lacing adjustments (see below) often relieve pressure.

Lacing techniques that change fit

Use the runner’s loop (locking loop) to secure the heel. Skip a lace eye over a pressure point for more room, or use parallel lacing for uniform pressure across wide feet. Small changes here can transform comfort without altering size.

Choosing the right sneaker type for fit needs

Not every sneaker shape fits every foot. Think about where you need support and where you need space.

Narrow feet

Look for sneakers with a snug heel cup and tapered midfoot. Models with overlays or internal heel counters help keep the foot secure.

Wide feet

Choose a roomier toe-box and flexible uppers. Some brands offer wide sizes-if a product notes a roomy last on its page, that’s helpful to know before you try.

Flat arches or high arches

We recommend trying supportive insoles for flat arches and cushioned insoles for high arches, and testing both under normal walking conditions.

Practical South African scenarios and tips

On hot Johannesburg pavements or Cape Town’s morning walks, feet can swell slightly-measure in the afternoon for a realistic fit. If you commute frequently, prioritise a comfortable midsole and a stable heel. For weekend braais or long market walks, pick breathable uppers that still have structure.

Common fit mistakes we see

Buying by the size number alone-different brands vary.
Trying shoes sitting down-stand and try under weight.
Ignoring sock thickness you’ll actually wear.

Final checklist before you buy

Measured both feet and used the larger measurement.
Tested thumb gap at heel and toe wiggle.
Tried a short walk for rubs and slip.
Confirmed returns/exchange policy for online buys.
