Skateboarding

Been skating for years, and I usually hang my back toe off and drag it to slow down. If you get a beefier set of shoes to skate in, like Half Cabs, they won't wear out so quickly. Otherwise you'll have to strengthen your ankles if they hurt from slowing down by stomping one foot off. Powerslides are fun, but a bit obnoxious to use for every time you need to slow down.

Carving is a good way to shed some speed, foot braking basically just put your foot flat on the ground and let it slide across creating friction which will slow you down. Powersliding on a board like that is going to be hard so unless you have done it before I’d try one of the other suggestions

Most of times I brake using my back foot on the ground. Little taps when i'm going slow, and rubbing when i'm fast. When i'm too fast i slide, but it's hard to do (like speed checks on a snowboard) you need quite a bit of speed with soft wheels. Hard wheels it's easy, just powerslide. Hit me if you need more details.

What I do is like pushing, but without actually pushing for speed. I've never heard it called pumping and I don't understand how it hurts your ankles? Anyway, with all weight on the front foot, put the back foot on the ground ground somewhere ahead of the toe side of the board. As you ride past it, you can use it to slow down. Don't scrape it or anything, just take it off the ground when it's back at your tail and put it down again somewhere further ahead again. If you're going fast it'll take a few "pushes" to come to a stop.
