I recently sprained my ankle and couldn't run (or walk). Once I could hobble around I put on my hiking boots which have some extreme ankle support and walked the dog around the neighborhood.

I was quite astonished that my stride was quite low energy. That is, I already knew approximately how many calories my watch reported if I walked (in my running shoes) the dog on a given route vs running that route. Apparently I had learned a much more efficient stride in the boot over the years, so I was able to walk the route in the usual time but by burning 20% fewer calories and at lower heart rate. I do a lot of backpacking so am used to long distance walking in those boots, but didn't know I used a different stride to do so.

This is all per my Apple Watch so take the measurements with a grain of salt. But at least it was like:like.
