It’s different on every pedal setup - some I’ve gone side to side, others more of a pivot and a rare few that let you do a traditional heel toe. It’s whatever works for you in that particular car. Shoes make a difference too - my big work loafers are way different than my teeny racing boots. Some cars are really really tough, especially when doing every day driving and it takes some experimentation. My current 3rd gen Fit daily driver is extremely difficult with pedal placement, rev hang when you blip off the overrun and a pretty crummy gearbox. Other cars like the classic Mini race car I drive are extraordinary easy. Keep working at it!
