Aiston, 28, has made more than 200 career appearances including a spell in
the Premiership with Sunderland and ended his four-year spell with Shrewsbury when his contract expired at the end of last season.
Wilson, 31, began his career with his local side Hull in 1992 and made 200
appearances for the Tigers before moving to Macclesfield in 2001.
"Steve Wilson is very bright and lively," Little told the club's official
website.
"He is a great trainer and has good hands and I think he will provide a really strong challenge to John Achterberg in goal.
"He has played a lot of league football and if called upon he can go in there and would make it difficult for John to get back in the side.
"I was looking for a winger with pace who gets at the opposition and I've found that in Sam Aiston. He's strong and is a six-foot lad and is very
quick and direct.
"Hopefully he will be a good player for us this season."
