It’s not too hard to see the difference here! The genuine club on the right is a true wide sole iron while the fake on the left is a normal width with a wide sole sticker. Another thing to note is the different font used on the number – and the underline used on the genuine club.
From the back we can see more differences. The badge displaying the ‘Wide Sole’ text on the left is from a cheaper print run and is starting to peel away at the edges. The genuine is still fully stuck to the carbon insert.
