***UPDATE Schuh’s response below LOOKS helpful, but it’s just a link to a chatbot where you wait forever for a human but nothing happens. The response was clearly to make them look helpful here, but it’s been a complete waste of more of my time***
It was hardly a major purchase, but I needed new laces for the Doc Marten's shoes I'd bought a few months previously (the laces supplied had develop weird lumps and wouldn't run through the eyelets.

The assistant who served me produced a pair of laces and told me these were the ones. I pointed to my shoes and asked "are you sure they're not too long?", she assured me that these were the correct laces, so I paid for them and left.

When I got home I discovered they were about three times the length of the original laces.

Honestly it's not worth me going all the way back there for such a small amount, but if you're thinking of buying anything there, you should know that at least some of Schuh's staff are either incompetent or don't care about giving you the product you need, or both.
