I'm in the same position. Some might say I don't need boots at all since I am only playing CQB indoors. However I still need ankle protection. My right foot and ankle have been weak ever since I had spinal surgery over twenty years ago.
What I don't want is boots that that have huge heels, with little flex in the soles, and weigh a ton. I don't care if they wear out quickly. If they are cheap enough, soft enough, and can be bent easily at the sole with your hands, they can be replaced as necessary.
So what I am looking for is something that looks like a boot and laces well above the ankle, but isn't really designed for hard conditions - an imitation boot if you like. 😄
Or trainers that run high up the calf.
Anybody got any ideas?
