With the guards in the shoes, is it uncomfortable to walk or run?
No, it will not make you uncomfortable because it is very thin, only 1 mm thick. You may need an hour or two to get used to it, or less.
Do they apply to adult, youth or kids shoe sizes?
Yes, we offer three sizes, and each size can also be cut to fit smaller, so whether they are as big as a size 15, 16, or as small as a size 3, 4, its no problem!
Can it only be used on sneaker shoes? For example, Jordans, Air Force 1, canvas shoes.
No, it can be applied to most shoes. For example, most sneakers, boots, skate shoes, casual shoes, etc., as long as they are not pointed shoes.
Some insoles are glued to the soles of shoes, what should I do?
You can install the protector directly without pulling out the insole, but you need to make sure it is installed in the right position. Pulling out the insole is only for easy installation and is not a necessary step.
