MOONSTAR BIOTef indoor shoes / gym shoes White x Blue, 23.5EE Mesh material, slip-on type. Velcro closure for easy width adjustment and comfortable wear. Purchased for use during rainy day gym practice with a sports club. Used approximately 4-5 times for about 3 hours each time. Home cleaned with oxygen bleach and a brush, but there are faint scuffs that couldn't be completely removed. Please refer to the photos. There were faint traces of name markings on the sides (about 2 cm on the inside of both shoes), which have been erased with white oil-based magic marker. They are not noticeable now, but writing your child's name over them would make them disappear completely.
