Re: Approval: For myself, personally, I am definitely in for meeting MERCS standards. Worbla is not listed as an approved material but I am happy to build and submit. There is a Dented Helmet Builder who recently built a female Mando out of WORBLA and she is getting rave reviews. I am not worried. Re; Boots : We can use boots with a WEDGE. We can cover laces/buckles with spats or armor. Personally, for me, I am hoping for minimum 3 inch wedge. If we design some kind of cover/spats.armor/for them, we can all select something that accommodates us and cover them for uniformity. Just a thought.
