Not as much as a ballerina but use just the forefoot, up to the arch. If only the toes were on the ground you might lose balance. With practice, the forefoot will keep your balance. But remember to have a standard boxing stance by bending your knees slightly. This gives you a bit of a "sitting" position, from which you can throw punches with power and move without falling forward.
HAD THe same problem learn 2 bounce, solved it for me if ur big like me prepare for some painful blisters but itll come
OH yeah, try moving your feet closer together it kind of forces you on your toes in a way and you can move much faster.
skipping makes you light on your feet definitely. Thats the sole purpose and the exercise, and coordination.
Some boxers are simply flat footed and will never have good balance or feel comfortable fighting on the balls of their feet or their toes. Being flat footed doesn't mean you can't learn to circle a bit, adjust your guard, learn how to duck, etc...
your balance will improve with thime,, being on the balls of your feet allows you to move in and out quicker
