Hoey led the field of seven Irish contesting the Castellon Masters in carding a four-under par 67 on the Club de Campo del Mediterraneno course laid out in an extinct volcano in Spain.
Scotland’s Paul Lawrie and Argentina’s Ricardo Gonzalez head the small 114-player field.
Hoey has been visiting England-based Dr Roger Hawkes, a sports medicine specialist who has arranged for the former British Amateur winner to fit special orthotic adhesive to both feet before taking to the course.
And despite still some discomfort in swinging the club, Hoey has been delighted with the results.
“I’ve always had bad feet but having the orthotic adhesive makes a big difference, and I’ve just got no aches or sore feet after my round,” said Hoey.
“I’ve been seeing Roger since Switzerland and he’s very good, as he also works with Chelsea Football team.
Fellow Irishman Gareth Maybin was delighted with the efforts of new caddy, Darren Reynolds in recording a three-under par 68.
“Darren was great and you can see his experience from working with such great players as Paul McGinley,” said Maybin.
Shane Lowry recorded a two-under par 69, Peter Lawrie signed for a 72, Paul McGinley a 74, Simon Thornton, 75 and Damien McGrane a 76.
Meanwhile Rory McIlroy continued the fight against his own swing at the Egyptian Open but he won the battle to survive the halfway cut after posting a disappointing second round of two over par 74 to lie ten shots off the lead.
However, he refused to blame the blustery conditions at the JW Marriott Mirage City Golf Club for his poor scoring, instead confessing that he has just not played well enough to come close to leader Lee Slattery.
“It was windy enough – quite tricky out there but it was really much the same as yesterday and I couldn’t really get anything going,” said McIlroy.
“I’m not hitting it great. It’s just one of those things. It’s not what I came to do but if I’m going into the weekend eight shots behind that wouldn’t be too bad. I’d take that.”
Colm Moriarty of Team Ireland signed for a second round of 70. Gary Murphy though adds another missed cut to his tally this season
