Actually worked on already tired feet!!!
Every year, I am on my feet for 3 days preparing for and setting up for a two-day 1k person event, where I then have to put on heels and host the events. - Last year my feet ached for days afterwards. This year I found and used Vivian Lou and it was a breeze! - Whereas last year I had to take multiple sitting breaks during the events in my heels, I didn't sit down ONCE during the events this year! These WORK! - I'm so pleased that the heels with the inserts are the only ones I'm wearing now. - HIGHLY recommend!
