Shawcross played more games than any other Stoke player under Pulis. He has been asked to adjust his role, looking for more short passes rather playing more directly towards Peter Crouch.
But he insists the side will not forget what worked under the old regime.
"It's been refreshing," he admitted to The Sentinel. "Obviously it's different. We're trying to play a bit more on the floor and I think we're adapting well.
"In periods against Palace I thought we played some good stuff, but we also mixed it up. Crouchy is still one of the best target men in the division. Overall I think we'll have a very successful season under the new manager.
"I don't think you can mess too much with the Stoke way. We're tough to beat, but we've got some quality players here, and Mark Hughes has recognised that.
"We don't want to lose our strengths, but we want to be better offensively too.
"We're not talking about rocket science. There have been a couple of tactical changes that have been implemented, and I think we've looked okay against Palace and Liverpool. We're looking forward to taking that on again in the next match."
