SMO Measurement Instructions

The numbers of the measurements given here correspond to those on the order form.

1. Horizontal AP at Medial Malleolus*: *This is a measurement unique to Galileo SMO, so it's important! At the Height of the Medial malleolus, measure the distance between the anterior and posterior sides of the limb.!Horizontal AP at Medial Malleolus2. Circumference from Back of Heel over Front of Ankle: Measure around the foot, following a path between the apex of the Heel to the Dorsum.

. Circumference through Apex of Arch: The path in which the circumference is measured does not have to be normal to the ground, it should fit naturally around the apex of the arch.

. Circumference over 1st and 5th Met Heads: This is also unique to Galileo SMO, so make sure you grab it! This must encapsulate the 1st and 5th Met Heads

. Circumference at Proximal Trim Height

. Width at Apex of Malleoli

. Height of Lateral Malleolus

. Height of Medial Malleolus

*9. Height of Desired Proximal Trim**

0. Width at Met Heads: Should not be taken as a straight line between the two met heads, rather perpendicular to the longitudinal axis of the foot

11. Posterior Calcaneus to End of 5th Toe

12. Posterior Calcaneus to 5th Met Head

3. Posterior Calcaneus to 1st Met Head
