Floor Mats Needed For O4' Expedition

I'M LOOKING FOR ADVICE ON ANY PARTICULAR FLOOR MATS THAT OTHERS HAVE PURCHASED FOR THEIR FORD. I HAVE SEARCHED AND FOUND MULTIPLE SITES THAT SELL DIFFERENT KINDS OF MATS AND HAVE BEEN UNABLE TO MAKE A DECISION ON BRAND/STYLE. I FIND MYSELF ON THE FENCE BETWEEN "CATCH-ALL" BRAND AND THE CUSTOM FIT STYLE WITH THE DIAMOND PLATE STYLE MARKING ON THEM. I LIVE OFF A GRAVEL ROAD ON A MOUNTAIN AND WOULD LIKE TO PURCHASE THE DEEP STYLE (DIAMOND PLATE STYLE) MATS THAT WILL KEEP MUD AND SNOW OFF OF THE CARPET. HOWEVER I'M NOT SURE HOW SECURE THEY STAY UNDER YOUR FEET. ALSO, I HAVE CAPTAIN SEATS IN THE SECOND ROW. I WOULD LIKE TO COVER THE CARPET ALL THE WAY BACK BETWEEN THE 2ND ROW BUCKETS SEAT TO THE 3RD SEAT. BELOW ARE SOME OF THE STYLES I'M CONSIDERING. ANY SUGGESTION WILL BE GREATLY APPRECIATED.
