From brogues and boots to Oxford shoes and loafers – British shoemaking label Grenson has been producing some of the country's favourite footwear since it was established in 1866 by William Green. Even after over 150 years in business, the brand continues to go from strength to strength – and given its meticulous manufacturing methods, it's not hard to see why.

Apart from Grenson’s more recent moccasin collection, all of the brand’s shoes are ‘Goodyear Welted’ – which is now a hallmark of all well-made British shoes, including the ones Grenson continue to produce today. This is a shoemaking technique that was invented in the mid 1800s and involves many individual processes, but the key benefit is that the shoes are strong and made to last a long time.

The main feature of Goodyear Welted shoes is the fact that the upper is stitched to a leather band called a Welt, before this is then stitched to the sole for added durability. In total, it takes up to eight weeks to make a pair of Grenson shoes and involves well over 200 individual operations, so you can rest assured that every pair of Grenson shoes offers a lifetime’s worth of comfort and support.

You’d expect Grenson's storied heritage to mean that every pair of its shoes fit and feel exceptional, and you’d be right. Grenson shoes come with their own letter sizing system; for men those specific letters are ‘F’ fitting and ‘G’ fitting.

Grenson Shoes sizing breakdown

‘F’ is a standard men’s width, so if your foot is on the wide side, you might have to go up a size for a little added comfort. However, the ‘F’ fitting shoe fits the majority of men. So, if you’re looking to buy a Grenson shoe with the ‘F’ fitting hallmark – which is detailed in the Size Guide drop down menu of each shoe – then opt for your normal shoe size.

‘G’ fitting is slightly wider than the standard men’s last but most men fit it perfectly as its always better to have a little room than too tight. Both the G and the F fit will be the perfect fit for most men.

Key points to consider:

  • Grenson fits to size. Take your usual size.
  • Grenson uses ‘F’ & ‘G’ measurements for all men’s footwear. Check out the drop down Size Guide on each Grenson shoe to find the perfect shoe width.
  • All Grenson sizes are based on UK sizing. Use the below size chart to find your size.
