السلام عليكم ورحمة الله وبركاته On the Construction the trousers go below the Ankle so dirt doesnt come into your shoes or skin. Does it still need to be above the ankles or can it be under for safety reasons? Barakhallahu Feek. May Allah bless you

Ustadh AbdulAziz al-Haqqan
If he can wear protection let him do so if he is not able to and it is necessary for him then yes he can wear them and Allah knows best
