Have you any solar shot with the foam board removed id love to see how you packed the foot? Why the foam board with i.m? I've only started using i.m since i came out here always used equipak at home, i.m wasnt available. Ive been using it alot here edss stuff but if i pack the whole foot with a bar wedge it doesn't stay in except under the bar.
I put mesh in between the shoe and the bar wedge, the shoe is rolled from the widest point forward which will also help hold it in. The foam board is to help keep it flat and to keep the dirt out of it while it sets. No solar pics without the board. Next go I will probably use a full wedge and magic cushion in the front half, went this way because all I had was bar wedges.
