Yep, there is a technique learning curve but it doesn't take long at all. I can ride in Vans now (with pins) and feel fine for mellower rides (otherwise it's Five Tens, every time). But one thing I'd say NEVER feels good is if I have something on like a trail running shoe or hiking shoe that has a lugged tread - that feels way sketchier. And the extra cushion of the sole doesn't give you the feedback you want. Fine for a casual or mellow ride, but not when things get rough. And even with Five Tens famous grip, if you want to shift your feet, you can in whatever teeny increments you want. Big lugs/tread make me feel "hung up" on the pins.
