37 Shoe Size in UK: Complete UK, US & EU Conversion Guide

If you’ve ever stared at a shoe size chart wondering why European 37 seems to shift between a UK 4 and a 4.5, you’re not alone. This guide breaks down the most common conversions for EU 37 across women’s, men’s, and unisex sizing, drawing from retailer charts and industry standards — including data from Foot Locker UK (specialist footwear retailer) and Famous Footwear (US shoe chain).

EU 37 in UK women’s sizing: UK 4 ·
EU 37 in UK men’s sizing: UK 4.5 ·
EU 37 in US women’s sizing: US 6.5 ·
EU 37 in US men’s sizing: US 5.5

The table below captures the key conversions for EU 37 across gender and measurement systems.

What’s size 37 in UK shoes?

EU 37 to UK women’s conversion

• EU 37 reliably converts to UK 4 for women’s shoes, according to Famous Footwear and Steve Madden (fashion footwear brand).
• Some unisex or youth charts may list UK 4.5, so always check the gender-specific table.

EU 37 to UK men’s conversion

• For men, EU 37 is less uniform. Famous Footwear places EU 37 at UK 5 in its men’s side, while Shop Nice Kicks shows both UK 4 and UK 4.5 in different rows.
• The discrepancy arises because men’s charts start at larger sizes, making EU 37 a borderline entry.

Bottom line: Women typically wear UK 4 for EU 37; men should expect UK 4.5 but verify with the brand’s own conversion. The safest route: measure your foot in centimetres.

The implication: if you’re a woman shopping for EU 37, UK 4 is the safe bet — but for unisex or men’s styles, double-check the chart, because one half-size up can throw off the fit.

Is a 37 a 6 or 7?

EU 37 to US women’s conversion

• EU 37 typically equals US women’s 6.5 (Foot Locker UK).
• However, some brands label it as US 6 or US 7 depending on their half-size rounding.

EU 37 to US men’s conversion

• US men’s 5.5 is the standard equivalent (Calculator.net).
• Shoe City shows EU 37 paired with both women’s and men’s US values in the same chart, reinforcing the split.

Half-size variations

• Brands like ASOS (online fashion retailer) sometimes map UK 4 to EU 36, making EU 37 fall at UK 4.5.
• The difference of one half-size can be critical for fit — especially in athletic or dress shoes.

The pattern: EU 37 lives in the grey zone between US 6 and US 7. Always check the brand’s own conversion before ordering from a US retailer.

What size is 37 in women’s shoes?

Women’s UK equivalent

• As confirmed by Famous Footwear, women’s UK 4 = EU 37.
• Ireand’s Pavers.ie (Irish footwear retailer) lists UK 4 as EU 37 in its women’s grid.

Women’s US equivalent

• US women’s 6.5 is the standard (Foot Locker UK).
• Some brands, especially in running shoes, round to US 7 — measure your foot to be sure.

Foot length in inches/cm

• Most conversion charts peg EU 37 at approximately 23.5 cm (9.25 inches) (Shoe City).
• Laughing Hens (UK knitting & footwear retailer) shows a similar cm length for women’s sizes.

Why this matters: centimetre measurements are more stable than label sizes. A 23.5 cm foot will fit EU 37 regardless of whether the retailer rounds up or down.

What size is 37 in shoes in Ireland?

Ireland uses UK sizing

• Ireland follows the UK shoe sizing system (Wikipedia (reference encyclopaedia)).
• Therefore, EU 37 = UK 4 in women’s and UK 4.5 in men’s — exactly the same as in the UK.

Example from Irish retailers

• Pavers.ie confirms UK 4 for EU 37 women’s.
• Guineys.ie (Irish department store) lists the same pairing in its size guide.

The catch: if you’re ordering from an Irish store that imports US brands, check whether they use UK or US labelling on the box — they sometimes differ.

Is a UK Size 4 an EU 36 or EU37?

Borderline cases

• UK size 4 is most commonly associated with EU 37 for women (Famous Footwear).
• But ASOS sometimes maps UK 4 to EU 36, creating confusion.

Brand variation

• Steve Madden lists EU 37 as UK 4.5, while others show UK 4.
• Shop Nice Kicks even includes both UK 4 and UK 4.5 in the same chart for EU 37.

The trade-off: EU 37 sits right at the boundary. If your foot measures 23 cm, you might wear EU 36; at 23.5 cm, EU 37. Always use the brand’s own chart — never assume a universal conversion.

Five conversions, one pattern: no single answer fits all brands. The centimetre measurement is the only constant.

One table, two patterns: most women’s charts converge on UK 4, but men’s and unisex charts scatter between UK 4 and UK 5. The variation isn’t a mistake — it reflects different reference lasts.

Six sizes, one steady pattern: each EU step equals 0.5 cm in foot length. That’s why measuring your foot removes nearly all the guesswork from size 37.

For UK shoppers buying EU 37 shoes, the choice is clear: measure your foot in centimetres, check the brand’s conversion chart, and order with confidence — or risk a half-size misfit.
