Along with a snap of the foursome, Wilshere wrote: "Positive week, managed to get through 20 minutes of ice skating without getting injured".
25-year-old Wilshere, who has suffered a succession of injury setbacks in recent years, is pushing for a more regular spot in Arsenal's Premier League starting line-up at the moment.
Hailing from Strasbourg, the eastern French city noted for its proximity to ski resorts, Wenger is well versed in such winter past-times and did have a word or two of caution for Wilshere.
"It's not ideal - for your balance it's not bad", Wenger said. "For a footballer I don't think it's great - it depends what you do".
"I don't know exactly [what he did on the ice]". Ice skating violently, I don't think he did that'.

Several other hedge funds and other institutional investors also recently added to or reduced their stakes in the company. The Fairview Capital Investment Management Llc holds 306,381 shares with $33.88M value, up from 292,906 last quarter.
The depth of midfield options available to Wenger has restricted him to four substitute appearances in the Premier League.
"I would say, yes, rotating the squad has been an advantage in term of injuries", he said.
Arsenal are looking for a response after Saturday's 3-1 Premier League loss to Manchester United, a match in which they forced David de Gea into 14 saves, a league record.
Wenger added: "They have been absolute outstanding, I must say".
"In training when I play the team from the Premier League against the one from the Europa League it is very hard to predict who wins the game".
'I'm always honest, I thought he wouldn't play but when he had the tests on Friday morning, he tried and he played. There is a fight going on.
