When is the best time of day to measure my feet for high-top sneakers?

Measure late in the day after activity because feet swell; this gives a more realistic length and width for choosing a high-top that won’t feel tight by evening.

Should we size up if one foot is larger than the other?

Yes - measure both feet and buy for the larger measurement so the bigger foot isn’t cramped, since high-tops can feel tighter because of their higher collar and extra upper material.

What fit features should we check on a high-top when trying it on?

Check that the ankle collar follows the bone without digging, that the tongue and lacing let you redistribute pressure, and that the sole profile and removable insole give the right balance of length and room across the forefoot.

How can we tell if the high-top’s ankle fit is right during a fitting?

Stand, walk and do a short sidestep and crouch: your heel should be stable with minimal slip, the collar shouldn’t pinch when you bend, and you should have natural ankle mobility; if you feel hotspots within five minutes, try a different size or model.

How to Choose High-Top Sneaker Size & Fit

Why fit matters more for high-tops

High-top sneakers change how a shoe supports your foot and ankle. They add height around the ankle and use more material over the upper, so a size that works for a low sneaker can feel too tight or too loose in a high-top. We help you focus on three practical outcomes: comfort when walking, enough room for socks and foot swelling, and a secure ankle feel that doesn’t rub.

Quick checklist before you measure

Measure late in the day - feet swell with activity.
Wear the socks you’ll normally use with the sneaker (thin sports socks or thicker crew socks change fit).
Have a ruler or tape measure and a flat wall space.

How to measure your foot at home

Follow this quick method to get a repeatable length and width measurement.

Place a sheet of paper on the floor against a wall and stand with your heel touching the wall.
Mark the longest point of your foot (usually the big toe or second toe) and measure from the wall to that mark in millimetres or centimetres.
Measure the widest part of your foot across the ball area to capture width.
Repeat for the other foot - buy for the larger measurement if they differ.

Convert measurements to sizes (practical note)

Size charts vary between brands. Use the foot length plus a fit allowance rather than assuming your everyday size will be right for every high-top. A common practical allowance is 8-12 mm of space from the longest toe to the inside front of the shoe for walking comfort - more if you plan to wear thicker socks or use insoles. When in doubt, choose slightly more room rather than less; a shoe that’s a little long can be tightened with lacing or an insole, but a shoe that’s too short will be uncomfortable.

Fit features to check on high-tops

High-tops vary more than low sneakers in how they secure the ankle and how flexible the collar is. Here are the parts to inspect.

Ankle collar and padding

A soft, well-shaped collar should follow the bone at the back of your ankle without digging in. If the collar is stiff, make sure there’s extra depth in the shoe so your ankle isn’t forced forward.

Tongue and lacing options

A padded tongue helps distribute pressure from laces; look for floating tongues (not stitched fully to one side) which allow easier adjustment. High-tops with extra eyelets let you lock the ankle for a snug feel - useful if you need extra stability.

Sole profile and insole

Soles affect how your foot sits. A flatter sole gives a roomier toe box feel, while a thicker midsole can reduce perceived length. Removable insoles allow you to fine-tune fit - useful if your foot is narrower/wider than average.

Trying on: a short fitting routine

When you have the shoes in hand, follow these steps to confirm fit rather than guessing.

1. Heel and forefoot check

Stand and walk a few steps. Your heel should sit stable with minimal slip (around 5-8 mm slip is acceptable). At the front, there should be the 8-12 mm allowance mentioned earlier - you should be able to press the front of the shoe and feel that space.

2. Width and pressure points

Walk on a flat surface and check for tightness across the ball of the foot. High-tops often feel tighter at first because the upper covers more area; move the laces along the foot to remove pressure. If you feel numbness or hotspots after five minutes, try the next width or a different model.

3. Ankle mobility

Do a short sidestep and crouch. The shoe should let your ankle flex naturally. If the collar pinches when you bend, try loosening the top eyelets or a size up; if the ankle feels unstable, use the extra eyelet to lock the heel.

Try both feet and walk for at least five minutes - short tests can miss hot spots that appear after a few minutes of movement.

Adjustments, insoles and socks

Small changes often fix fit without changing size. A thin-performance insole can take up 2-4 mm of space and improve arch support. Thick crew socks add bulk; try medium-weight cotton or a performance sock if you’re unsure. If a shoe is close but the width is slightly wide, add a heel cushion to prevent slipping.

When to size up or size down

Size up when you plan to wear thick socks, use orthotics, or if the toe allowance is under 6 mm.
Size down only if the shoe is clearly long and your heel doesn’t slip more than ~8 mm; otherwise prefer a different model in your usual size.

Buying online - what to check on product pages

Online shopping is our everyday rhythm. Look for these signals on product pages: a brand size chart, insole length in centimetres, notes on whether the shoe runs narrow/wide, and user reviews mentioning fit. When available, check similar models in the Sneakers category for consistency between ranges.

Returns and alternate sizes

Plan for a single exchange if you’re between sizes - many of us keep a pair for a day or two and return the variant that didn’t work. Note return windows and whether postage is covered; these details make trying a second size less of a chore.

Practical South Africa examples

If you commute by foot in summer, expect feet to swell and prefer a little extra length. For winter wear with thicker socks, size decisions can go the other way. Typical retail price bands for everyday high-tops range widely; a comfortable mid-range pair often sits around R1 200-R2 000 depending on brand and materials, and insoles or lacing upgrades can be R150-R400.

Final check: fit score

Length: 8-12 mm toe allowance - 2 points
Width: no numbness, minor pressure adjustable by lacing - 2 points
Ankle: secure but not pinching - 2 points
Walk test: comfortable after 5 minutes - 2 points
Sock/insoles considered: yes/no - 2 points

A score of 8-10 means a good match; 5-7 suggests adjustments; under 5, try another size or model.
