A good drill on sidestepping to gain angles when fighting (a fighting “kata” if you will :-). Boxing footwork has had a huge influence on modern karate, and with good reason. The traditional methods of the kata are perfect for close-range civilian self-protection, but if we also wish to include a fighting component to what we do then we need to have the footwork skills for closing distance and negotiating a back and forth extended exchange. Personally footwork is one of those skills that I love to train because my body likes the “feel” of it.
All the best,
