SHOE-MASTER Recommendation

Answer a few quick questions and we’ll guide you to the best OSZEA size — based on your product, foot length and fit preference.

Step 1 of 6SHOE-MASTER
Step 1

Which OSZEA are you sizing?

Fit can vary by style, so we tailor the recommendation to the exact pair.

Step 2

Who is it for?

Tasman and Urban come in Men’s and Women’s sizing. Kids Melbourne Chelsea uses Kids sizing.

Step 3

What size do you usually wear?

Enter the US / AU / NZ size you usually wear. EU and UK are optional and help us cross-check.

Not sure? Skip this and add a foot length on the next step — it’s the most accurate.
Step 4

How long is your foot?

Measure from heel to longest toe. This is what makes the recommendation accurate.

Measure both feet and use the longer one. See the measuring steps below if you need a hand.
Step 5

How do you like your shoes to feel?

This nudges the recommendation when your foot sits between two sizes.

Step 6

How would you describe your feet?

We size by foot length first, then give you width-specific advice.

Measure in a minute

How to measure your foot

The most accurate way to size up. It only takes a minute and a sheet of paper.

Step 1

Paper to the wall

Place a sheet of paper flat on the floor, one edge against a wall.

Step 2

Heel to the wall

Stand with your heel firmly against the wall, weight evenly on the foot.

Step 3

Mark the longest toe

Make a pencil mark at the tip of your longest toe — it isn’t always the big toe.

Step 4

Measure heel to mark

Measure the distance in cm or mm. That number is your foot length for SHOE-MASTER.

Measure both feet — and use the longer one
Most people have one foot slightly larger. Sizing to the longer foot avoids a tight fit.

Quick checks

Not sure? Troubleshoot your fit

Run through these quick checks before choosing your size. Tap a question to see what we’d do.

Check your foot length first. If you prefer thicker socks or a little extra room, choose the larger size. If you prefer a closer fit, choose the smaller size — but only if your foot length is safely within that size’s range.
Choose your size based on foot length first. Then, if you prefer more room across the foot, consider sizing up. Our 30-day exchange makes it easy to adjust if the first pair isn’t quite right.
Choose your regular size if there’s enough room for your foot length. If you’re already between sizes, size up to leave space for thicker socks.
Measure both feet and use the longer foot. If your child is between sizes, choose the size that gives comfortable growing room — kids’ feet grow quickly, so a little space helps the boots last longer.
A new pair can feel structured at first, but it should never feel painful. If your toes are cramped or the foot feels squeezed, re-check the size chart or contact OSZEA — we’re happy to help you find the right size.
Try them with normal socks and check the heel movement. A little is fine, but if your foot slides too much, you may need a smaller size. Re-measure your foot length and compare it with the chart to confirm.
