John Bull offers a range of unisex styles and our sizing is based on a UK sizing comparison (not a US sizing comparison). If comparing a US size deduct one size as a general guide. For women’s sizing, we suggest deducting three sizes from your usual UK women’s size to find your John Bull size. For example if you normally wear a women’s size 7, a John Bull unisex style in size 4 should fit. See our size conversion chart to assist with finding your John Bull size.
You can also use our handy foot measure to check your size. Please download our foot measure chart and follow the instructions.
