Deer, goats etc make noise when they are walking in those conditions. Try to simulate what a deer/goat does and walk like them. Go slow, stop every few paces and use your eyes....
Have a look at this.....

If you do step on a stick and break it, dont move any further........I normally 'freeze' and without moving my head use my eyes to scan the area for any movement. Any deer hearing a stick break will lift its head and move it around trying to locate the source of the noise..........If you keep moving they will run immediately.
I also have a couple of camo hoodies which I had made.......the hood part is a lot bigger than the ones you would buy and I can wear a cap under them. The cap bill keeps the front of the hood off my face and keeps my face in shadow. By stopping immediately I snap a branch I can scan the area with my face hidden using just my eyes.
The most important thing in those conditions is to move slowly in my view.......
Your mileage may vary....
