Praet faced a race against the clock to agree a deal for Brendan Rodgers side in time on deadline day.
The midfielder revealed he signed “just in time" but could not return home and collect his boots, even playing with a team-mates pair for his first game.
Praet told the Guardian: “It was a really close call because it was deadline day.
“I arrived at the training ground but there were some small issues with the contract and I think it was only one hour before the deadline that everything was figured out, so I signed just in time.
“But I arrived here with the thought that if I sign, I could go back to get my stuff I needed.
"But the gaffer really wanted me to stay for the first game, against Chelsea.
“I had no boots, so I did two training sessions and the first game with somebody else's. I don't even know whose they were."
