Just an anecdotal post saying thanks to Dr Blake

I've been reading for many years how, the reasoning behind, and the technique for making a Blake inveted device from his web site, publishings, and posts and blogs.

So a few months ago I started prescribing making them direct milled for my customers in conjunction with Phil Wells who does the Cad-Cam work. They have been a great success giving exceptional supination control while making shoe fitting much easier because of the reduced bulk compared to a more conventional posted orthosis.

This method works best for the flexible /compliant foot that has a natural cavus foot shape but is pes pancakus on weight bearing and extremely pronated to the max so the subject tend to walk on the medial border of the foot with the latreal border non w/B,ing.

What we do at Foothouse is take a non weight bearing PoP cast with 1st Ray plantarflexed with the heel inverted and the forefooot everted and the STJ around neutral. Then we take a weight bearing RCSP foam impression. When the the device is milled we position the arch height half way between the w/b cast and the PoP cast arch height. Then we add a 5dg DC inverted wedge and obliterate all the heel cup.

We have been making an addition of a high medial arch flange and then filling with 8mm red poron 'D' - this really enhances the foot comfort and the natural cavus foot shape.

works really well so Thanks Dr Blake - another useful tool in the box.

regards Dave Smith
