I do  lot of walking and hiking.  Unfortunately I started having metatarsal pain.  I bought Spenco inserts for my running, hiking, and dress shoes; and they did a great job of relieving the pain, at least for the first six miles.

However, I still experienced pain with my padded Sanuk sandals, so I purchased a pair of these and presto - instant relief.  Unbelievable.  I wear these around the house all day and on shopping trips, virtually pain-free.  I also bought the Spenco open toe sandals for when I want to wear socks.

I very highly recommend these for folks with metatarsal pain.
