Since "Sundance safety half-boots CN-25L" which I purchased earlier has got a little tired, I tried purchasing this product in the same price range. Since our feet are wide Takashi Kai, Wise 4E is a prerequisite condition. When bending the toes and squatting position, the toes end bracket bites in a bit. Velcro belt is short overall, so it may be bad for the thicker calf to belt. The material of the shoe is also a little hard, I use it for about 7 to 80 hours but because I am not familiar with my feet, I feel tired very much. Again I will purchase "Sundance safety half boots CN-25L" again.
