They look overpriced, seeing as how you can buy pedals for less than the extenders, but the cost is still low and would be worth it if they help your knees.
Doesn't necessarily have anything to do with the size of your feet. My shoe size is 9 1/2 - 10, but due to arthritic ankles (the right one is noticably worse than the left), my feet point outwards a fair amount. You can get by with flat pedals, but there will be problems with clipless pedals. For whatever reason, I cannot unclip in the usual way of rotating your heels outward. I have to rotate them inwards. The extenders also help in this regard.
The guy at High Sierra told me that they wait to accumulate a group of orders and then submit the batch to a machine shop. I took a guess at what it might cost to have a pair made at my friend's machine shop and you couldn't have a one-off made as cheaply as High Sierra or KneeSaver can do. It's a reasonable price...
