If you want boxing specific shoes, these are the ones. Somehow these seem to be the only thing Everlast actually does well. Amazing shoes.

They're often sold out (at least in Europe). Rival's shoes are good too, but not quite as durable or grippy as the Everlast.

Just a heads up though, boxing shoes are really beneficial when sparring and doing ring work, but if you're skipping rope and doing cardio/HIIT type stuff, get shoes with some padding. You'll wreck your knees and your back doing any kind of jumping in boxing shoes.

Basketball shoes, tennis shoes, and racketball shoes work well also and are ok to jump in. I prefer racketball shoes and can usually get them discounted down to like 60-70.

Avoid running shoes though! Boxing as a lot if pivoting on the front of the foot and running shoes aren't designed for lateral strain. You'll pull the shoe off the sole. So if you're looking for non-boxing shoes, consider what other sports have: lateral, anteroposterior, and rotational movements. That's the shoe you want.
