I have a ruptured ankle tendon along with an accoustic neuroma causing me a great deal of instability. Because of my age Doctors have not recommended surgical remedies for either problem.  They suggested a stable shoe such as New Balance which is the brand I had been wearing these last few years. While New Balance has given me a good deal of stability, they are clunky, stiff and heavy. Last christmas, my son's gift was a pair of Montara II hiking shoe in the same size 11 as the New Balance. Viewing the gift with a lot of sketicism, I started wearing them and found they decreased my pronation and gave me much greater stability. It was a lighter shoe along with a narrower heel while still providing adequate toe space. I have not gone on any hiking trails. Nor have I worn them for hours on end but for the frequent few hours I have worn them grocery shopping, walking 5 blocks to a movie or library, I've not gotten any blisters. What I have done is purchased another pair just because they feel good and I like the colors. Both my doctor and therapist like them too.
