How should safety shoes fit? UK size guide

A toe cap doesn’t stretch, so fit matters more in safety footwear than in trainers. Here is the 5-step fit check, a UK to EU size chart and when to size up.

Quick answer

Your toes should not touch the toe cap: leave about a thumb’s width (around 1 cm) in front of your longest toe. The heel should be held with little or no slipping, the widest part of your foot shouldn’t press against the sides, and you should try them with your work socks at the end of the day, when feet are largest.

The 5-step fit check

1

Toe space

Stand up. Press the front of the shoe: there should be about a thumb’s width between your longest toe and the end of the shoe, and your toes shouldn’t touch the toe cap when you walk or crouch.
2

Heel hold

Walk around. Your heel can lift a few millimetres, but it shouldn’t slide up and down.
3

Width

The widest part of your foot should sit at the widest part of the shoe without pressure on the little toe or bunion area.
4

Crouch test

Crouch as if picking something up. If the toe cap digs into the top of your toes, try a half size up or a different shape.
5

Sock test

Always try them with the socks you work in. Thick work socks can take up half a size.

A toe cap won’t stretch

Leather and mesh soften with wear, but the toe cap never changes shape. If your toes touch it on day one, they will still touch it in a month.

How to measure your feet at home

1

Late in the day

Measure in the afternoon or after work, wearing your work socks.
2

Trace your foot

Stand on a sheet of paper against a wall and draw around your foot, keeping the pencil upright.
3

Measure the length

Measure from the back of the heel to the tip of the longest toe. Do both feet and use the bigger one.
4

Compare with the chart

Match your measurement to the size chart on the product page, then add a little room for toe space.

UK to EU size chart

UK	EU	UK	EU
4.5	36	7.5	41
5	37	8	42
5.5	38	9	43
6	39	9.5	44

Sizes vary between models, so always check the chart on the product page. For example ELYTLITE+ comes in UK 4.5–10 (EU 36–45) and ELYTGUARD in UK 6.5–12.5 (EU 40–48).

When to size up

You are between sizes
You wear thick work or thermal socks
You plan to add a thick insole or orthotic
Your feet swell a lot during long shifts
The toe cap touches your toes when you crouch

Removable insoles help

If you size up and the shoe feels loose, a cushioned insole fills the space and adds comfort. See our insole guide.

Frequently asked questions

Should safety shoes be tight or loose?

Neither. Snug at the heel and across the middle of the foot, with room for your toes to move and not touch the toe cap.

Do safety shoes run small?

Some models feel smaller because of the toe cap. Check the size chart for each model and leave about 1 cm of toe space.

Can I wear my normal trainer size?

Often yes, but check the chart, especially if you wear thick socks or insoles. When in doubt between two sizes, many people choose the larger one.

How do I know if my safety boots are too big?

If your heel lifts a lot, your foot slides forward or the boot creases deeply in the wrong place, it may be too big. Try tighter lacing and an insole first.
