Shoe size 34 is usually a small EU size that converts roughly to:

  • EU 34 ≈ UK 2 (women/kids)
  • EU 34 ≈ US 3.5–4 (women) (often listed simply as US 4)
  • Foot length: about 21.3–21.4 cm

Because brands differ slightly, always check the store’s specific size chart and, if possible, measure your foot in centimeters and match it to their EU 34 row.
