These are the ideal black kung fu or black karate shoes for many types of martial arts training and are great shoes for casual wear so you are always ready to spring into action.
Outside shoe measurements are::
Size / Length x Width cm:
size 4 / 23 cm x 8.5 cm
size 5 / 24 cm x 9 cm
size 6 / 25 cm x 9 cm
size 7 / 26 cm x 9.5 cm
size 8 / 27.5 cm x 9.5 cm
To find out what size you are just look and measure the shoes you have.
The karate shoes are a thin walled shoe so there is little difference between the inside and outside measurements.
When you exercise your feet swell, so you are usually better off with a slightly larger shoe.
