hoof was wearing fast from my couple road trips so took the tire sock idea and using zip ties made hoofies and raptor legs.
Hoofy cut from 20x1.75" bike tire. (cut wire on the edge of the inner side of the tire with wire snips. Rubber can be cut with razor blade, exacto or box knife etc.)
1. 2x Cut from tire an amount same length as hoof
2. in 4 corners of each piece JUST UNDER the metal wire that is on the outer edge of bike tires; place a small hole or slice in the tire.
3. First for one Bock then the other; insert zip ties thru holes and the bracket the locks the end of the Bock's spring down; as shown in drawing (red). Zip ties pull against wire in tire so it should not pull thru the rubber, but time will tell. My zip ties are black also.
4. Line it up careful as you go and tighten the babies up.
I used 20" tires so I could use the remainder to help cover the springs. Last week discovered the place in town w/bike tires was closed so I used pipe insulation and athletic tape to protect the springs.
Raptor Legs
Cover insulation foam over springs with the rest of the bike tire from above... hence the name
raptor legs cause of the ruff bike tire skin makes it look knarly :

. Cut in 1/2 the remainder of bike tire
. With good sewing sissors cut off the inner edge of the tire that has the metal wire in it. (it just formed to the shape I wanted better after doing this) To my suprise it cuts easily off
. Zip tie this too the INSIDE of the spring. Remainder (mine was 22" remaining) should be just enough to cover most of the inside of the spring and padding.
. *Purchase two more 20" bike tires (8 bucks each) and cut them to cover the out side from hoof all the way to the top of the spring (34"?).
. Might have to cut it making two seperate pieces. One from top of spring to where spring goes into metal channel at bottom. The other is the rest from top of metal channel to hoof plate. Say this cause do not know if this joints flex will be limited by a one piece tire cover on the outside like described above.
. Might be enough tire left over to cover the inside of channel from hoof to foot plate arm to complete the raptor leg look.
*discovered this last part little late and thusly this section is speculation / idea stage only. Will do this final bit myself later.
