Thanks for the links, Kaelle. No, they didn't come with any instructions, which was a pain as they are expensive gloves. In the end, I just rinsed them in warm soap and water, let them dry and then stuck my hands in to get them into shape. Next time I'll follow the advice on the first link you sent.
I am sure you have already checked inside for a care label if any. If there is a brand name on them I would google for a website to see if they have info on them there.
