Checking the review beforehand and purchasing a small one is a big right answer Just because the top of your feet is a bit high, the corner of the protection plate gets a little stress when wearing it for a long time . Working on places where oil is inevitable for work, it is very helpful to not slide at all.
I chose this because the Velc tape type seems to be tightened securely. I think that it is easier to take off or wear it than the things of Fuji shoes I used to use. It is a thank you if you can take off or wear it quickly more easily.
