even good tennis shoes only last a couple of months
at best before there are any holes in them, so i would
suggest looking for a tennis shoe design that you like
and hope that it has a 6 month warranty on them...
even though it might seem like volleyball shoes might
be easier to move around with when your playing tennis,
it would only last a couple of weeks, depending on how
often you play tennis, before they start to wear out..
n then you'll just be out of luck since you'll have no
shoes for tennis AND no shoes for volleyball..
