I have been walking 5 miles a day for like 20 years. About six months ago, I developed an acute debilitating atrocious pain in my right foot out of absolutely nowhere and for no apparent reason. (Pain was "almost" as bad as getting an anal fissure repaired a couple decades ago - ouch.) Was at the point of needing crutches. Podiatrist diagnosed plantars and prescribed these inserts. WOW. After two weeks of wearing these inserts, barely a hint of plantars. Have walked even up to 10 miles straight. I go six feet and 260# too - no skinny winny here @ 62 years young. Only issue is these wear out / develop holes in the heel sections with heavy use, at least with my gait style. But I will NEVER not wear them - FOOT AILMENT HEALED!!! :) Highly recommend.

These insoles are marvelous I have used these for years. My therapist was quite impressed at the quality for an over the counter insole. My heel and arch pain are history with these insoles.

I decided to try these orthotic inserts out after spending 6 months using Superfeet Blue inserts to help alleviate pain in my left heel and arch from plantar faciitis. The Superfeet Blues were fine as an everyday alternative to the regular removable footbeds in most of my shoes, but for the dress-ier shoes that I wear at work 5 days-a-week, the Superfeet simply did not offer enough cushioning to provide any relief. I decided to try something else and arrived at the Powerstep Pinnacle. I am pleased thus far. I've used them for about a week in my work shoes and have noted the following:

a. They provide much more cushion than the Superfeet, particularly in the heel.
b. They are thicker and slightly wider than the Superfeet and take up more room in the shoe.
c. The arch bump is larger than in the Superfeet Blue and takes a little getting used to.
d. They do not squeak nearly as much as the Superfeet inserts (good grief this was annoying).

The biggest difference is the material. The Powerstep inserts are made with a softer, but more voluminous foam material. The Superfeet Blue are made from a thinner, but much more rigid foam. They also have a hard plastic heel stabilizer on the bottom which, yes, does offer heel support, but does nothing whatsoever to relieve pain. If anything, it made the repetitive impact on the heel from each step worse.

My own experience has been that the Superfeet Blue are OK, but not terribly effective for addressing my plantar fasciitis. After a week's time, the Powerstep Pinnacle has provided immediate relief from the pain and, hopefully, will put me on the road to recovery.

My son is a corrections officer and is on his feet for his entire 8 hr shift. He has completely flat feet and was having terrible pain in his feet until I bought him these insoles. Not a complaint since them!! They are a miracle! Will be getting a new set when he wears this set out. He also had a $300 set from the Doctor that did not work.

If you have medium to high arches, you may want to read this. I have tried a few of the Spenco products, the Superfeet black insoles, the Birkenstock burkosport arch supports, the Sorbo orthotic arch insoles, and the Powerstep original arch supports.
Of all these products, I find the Powerstep products to be the most comfortable for my 10 hour days on a concrete hospital floors. Although, I have had the Pinnacle's for under a week, the arch support is excellent, and the cushioning is good in the forefoot and heel.
At this point, I cannot comment if they will be durable long term, or how they may be in 3 to 4 months. So far, the Pinnacle's are among my favorite's.
