Timberland PROMen's Direct Attach 6 Inch Soft Toe Insulated Waterproof Work Boot

What is the difference this and the premium 6 inch boot? also, are the sizes stated in men or women’s? i noticed an m beside the sizes.

Good for walking on snow?

i am usually a women's size 9 in shoes but when i look at the size chart for these boots and i measure my foot it says i am a size 7. what size am i?

Are these steel toe?
