Relieved pain from my Mortons Neuroma between my middle toes. Also relieves plantar fasciitis. The inner arch comes up slightly higher than the Birkenstock sport insole with the dark blue companion insert, so if you pronate this will give you the support you need. If you already are accustomed to wearing Birkenstock shoes or sandles, the firmness of the arch and the fact that they need a short breaking in period will not surprise you. Easy to switch the inserts between different shoes. The inner arch is high and will show on ballet flats. Recommend taking the arch with you when you buy new shoes to see if they accommodate the arch and you have enough room in the toe box.
