Yes but if it does not have ankle support you can hurt your ankle and it may not have good grip
a normal shoe can be use in playing basketball it is just that hightop shoes are more looked for because they give more ankle support.
Use flip-flops if that's what u got. Just get out there and take some jumpers!
