I got plantar fasciitis from skateboarding, pushing with that left foot. So what did I do? Switched feet, of course, and got it in the other foot.Then I could not walk when I got up..got orthotics, they are essential, but so is DAS night splint BOOT!It is a miracle device. It relieves the torture of trying to stretch your arch against the other foot while in bed, or against the bed board, or the sheets. It will give you the first real relief from acute plantar fasciitis. it even works for leg cramps. BEWARE tho if your other foot is sensitive and bare, it hits against this hard boot with things sticking out. Hurts my ankle bone one other foot. It is also heavy enough to make your knee go out if you have a really bad knee like mine, so caution knee trauma victims, consult doc as to yr strength, or use common sense.CAUTION HAMMERTOE, CORN OR BUNION Sufferers: The side of the toe bed are bent up at a right angle...so it HURTS my corns on my hammer toe. I had a Royce before and it must have been large as it also has this stupid edge on toe bed but I was not hitting it. So get a size up if you suffer from this or super wide feet, as I am a female with fairly narrow foot, men's 71/2 offically, . I might try out one of the kind that have padding on them altho they look hot, I have cold feet. Also, you can't get "either foot" in a super expensive boot. You have to pick one side. I like to switch from foot to foot as one still has a bit of fasciitis and a loose ankle and the other often gets cramps in the early morning. This is a pretty decent boot, fairly light.Royce had much more adjustable straps than this boot, but I don't know how they are now, that was years ago (if it breaks, fix it with duct tape. most likely they break in the strap that keeps your ankle flexed, especially if you like to crank it up tightWhen the boot hurts your other foot put a skinny pillow there, or cover the booth with a giant christmas stocking. Or wear two!Oh, and I hate to break it to you guys but often PF is for life, so get those orthotics, they do help,:when I stop wearing them my PF comes ripping back into me. Do that stretching and massaging too. If you ride a bike, take off the toe clips and put your arch on the pedal, or even use those pedals for cleats, that are like a post sticking out, they feel great on your PFasciitis.I CANNOT LIVE WITHOUT MY NIGHT SPLINT BOOT! (altho i want a lighter softer one)

*** I'm putting this review on all sizes of this product, sorry for any redundancy. I'm hoping it will be helpful for anyone considering it ***I have been wearing this splint for about a month now to combat a pretty severe case of plantar fasciitis and want to update you on the effectiveness and my experience with it. My plantar fasciitis was caused primarily by weighing too darn much, plus moving into a house with mostly hardwood floors and walking around barefoot/in socks without foot support. I had never heard of the injury until it was too late.First of all the product. I started out with the medium size based on my shoe size but my toes stuck out over the edge and my foot felt kind of squished so I switched to the large. My foot size is "around" 10 or so, I would suggest going to the large if you have any question.How I adjusted the straps. The top strap keeps the thing from sliding up and down and as such I have that one somewhat tight. The middle strap (goes kind of over your ankle) is important in that it keeps your foot in the proper position. If too loose, your foot can position so that the ligament is not stretched properly and can tighten overnight. So I tighten this strap as much as comfortable so that my ankle can't bend and separate from the device much. If you find you can point your toes downward, then this strap is probably too loose. The bottom strap (over the top of your foot) is not as important in positioning as long as the middle ankle strap is correct, and I have that one quite loose. The bottom one if too tight is very uncomfortable and cuts off circulation in my case. As far as the side straps, pull them tighter to increase the stretch, generally just a gentle stretch is all you need. If you change these side straps much, you will need to adjust the other 3. This is just what finally worked fairly comfortably and effectively for me, your experience might be different. I definitely agree it does take some getting used to.Effectiveness - I had immediate relief for that "first step" in the morning. I was able get out of bed and walk normally where before using this product I was hopping around on my good foot for about 5 minutes. I could not put any weight at all on my bad foot. My foot pain was not entirely gone, but felt just "normal" as though it was during the day. I also now have orthotics designed for plantar fasciitis in every pair of shoes/slippers I own (fortunately I am male so that is not many ;-)..) and am very careful not to walk on any non-cushioned surface without these orthotics.Is my injury "fixed"? Not yet. I think if I were to go a night without this splint I would still be in a lot of pain in the morning. So this has reduced/eliminated that problem but I still have to wear it and of course the goal is a "cure" and no longer needing to wear it. I have a feeling that overall my problem is improving, and if I continue to wear the orthotics and use this product it MIGHT over time go away. It took a long time to get the injury and I'm just trying to be patient in my self-treatment of it. At some point I may see a podiatrist but for right now this is sufficient.I'll update this review if I have any major breakthroughs.In the meantime, I would recommend it highly at least for relief of morning pain.***** Update 9/28/10. My foot has been feeling better so tried a couple nights without the splint. It wasn't as bad as before (about like after an hour or two nap) but gradually worsened. I started wearing it again and better in the morning and all day. Just have to be PATIENT I guess. But the goal is to not hurt/injure the foot so anything which prevents pain is important. Just not ready to stop wearing it yet. But I'm hoping soon with the other steps, not quite yet. Still keeping up with the orthotics.***** Update 11/18/10 (last one). I think I've reached the break-even point where the inconvenience of the splint (although not bad) outweighs the benefit I get. At most 10 to 15 seconds of stretch is all I need now in the morning to be quite comfortable and now I'm also quite comfortable all day. I still use and will continue using inserts (plus have lost 23 lbs, yay, 44 more to go). But for now I consider my plantar fasciitis if not cured, at least very livable and tolerable. I expect it to continue to improve still.Was this product worth it? It certainly helped with the extreme discomfort and for that I would definitely recommend it. I'm not sure that it helped with my (near) cure, but it certainly wasn't a good thing to allow that ligament to tighten up so badly every night. I'm fairly convinced that the overnight stretch did at least speed the process. If you can stand to wear it, I would say it is definitely worth it.
