i agree w/previous reviewer.
this is a shoe specifically designed for dancers.
having danced for years & then moved into fitness,
these are perfect for karate.
there is no ankle support & due to the split sole,
if you have arch concerns --- not the shoe for you.
i ordered the 9/10 --- a little big, but i'm an in
between, so i'll make due w/peds.
very light & nice design.
good for yoga (if you prefer your feet covered)
& pilates.
if you're a dancer acquainted w/ capezio sizing,
order down.
