I got drop foot in both feet from a genetic blood disorder that caused some serious nerve damage in Nov. '06
I had some plastic articulated AFO's that pretty much came up to me knees. As my overall leg strength came back, I had the AFO's cut down about 8 inches above the knee, which made them more comfortable and cooler.
In this last month, I had two more pairs made. One is made out of a much lighter and pliable plastic and is still just as supportive and fit a little better into shoes.
The other pair, has been mentioned before, the silicone pair called SAFO's made by a company in London. I am looking forward to becoming more active and cycle again someday, so I thought these would be more comfortable. I just got them last week and they are definitely more comfortable. However, it does not hold my foot up long enough such that I can roll through a step, so in other words, my feet slap when I walk. My foot clears, but the walking biomechanics are wrong. I am working with my orthotist to see if I can get recast with my foot in a different angle so that I have a greater foot lift. With this said, I do like them am going to ask my physical therapist if the MBT shoes in conjunctions with the SAFO;s would be ok if I have to keep my current pair. BTW: my foot drop is pretty severe, so if you have mild drop foot, the SAFO may work well.
The company is called Dorset Orthopedics and they have been very responsive to my many questions. There are no places that have used them in the West Coast that are listed on the list they will send to you if you ask. Fortunately, Loma Linda Prosthetics Dept was willing to work with me to get them to me...they are an awesome group. Just be aware that it can be a pain to get your casts and final product to/from London, so ask for shipping suggestions from Dorset. Secondly, remember the dollar is really weak compared to the pound, so they are costly, but my insurance paid 90%. Thirdly, ask your orthotist to writed "Trial Pair" on the casts so that you can return them if they do not work. Lastly, as of today, they do not accept purchase orders or checks from companies in the US...only credit cards or a wire transfer, which is a little ridiculous given that Loma Linda is pretty well known, but that is how it is.
Anyway, if and when get my new pair, I will try and remember to post again to tell you how they are..
BTW: I have the pair with velcro on the outside, so it is not as aesthetically pleasing as the pair which have the velcro on the inside and thus hidden (and more expensive of course).
Good luck.
