US 4 shoe size questions

What size is this collection?

This is the men's US 4 collection. The title also shows 5.5W for women's US 5.5 and 37EU for the store's EU guide.

What do W and EU mean?

W identifies the women's US equivalent shown in the collection guide. EU identifies the European size reference. Plain shoe sizes in our listings are treated as men's US sizes unless another sizing system is explicitly stated.

Can I shop here if I wear women's US 5.5?

Use this collection as a starting point for women's US 5.5. Check the actual pair's label, width and brand guidance because model-specific fit and conversions can differ.

Why can the product label show a different number?

Designer brands can use their own sizing systems. A listing may show the original designer size alongside an explicit US equivalent. Use the product details and brand guidance to confirm the pair rather than relying on the collection title alone.

Does every pair fit true to size?

Fit can vary with the model, width, materials and prior wear. Review the product photos and fit notes, and compare with the same model when possible.

How do I confirm that my size is available?

Open the product, select your size and check its stock status. A product may have multiple size options, and stock can change.
