They have come off on the sides after the first year.
Where it folds when you walk, it has started to deteriorate to a great extent and slips very easily with the slightest thing dangerous when I hold the machine or try to push it.
The use I make of them is very normal. I only wear them on trips and don't walk in them. They are not even worth 30€.
Really bad.

They have a mediocre fit, I haven't needed to learn if they protect or not, but after relatively little use, they have enough wear and tear, they won't last much longer

Unfortunately, although they seem practical, they did not withstand the test of time. They broke very quickly, with the first sign being the side zipper. I would not buy them again.

Poor construction quality is evident as soon as you hold it in your hands. The shoe's tip touched the asphalt lightly three times and the soles disintegrated from the inside. (I have had shoes touch asphalt in turns before, but I have never seen anything like this.)

Very good construction materials, durable and with excellent fit. Choose your regular size. Good and economical choice

Quite good construction. It has an issue with the inner seam on the side of the little finger (the seam touches).
It would be good to try it on in a store before ordering so that you won't be disappointed afterwards.
