I’m simply writing in my gratitude for your help and my happiness with how well the inserts are working. I am a flight attendant and on my feet for easily 8-12 hours a day on average. Your custom orthotics have truly helped in alleviating the tired feeling in my feet after a long day of work, especially in my arches. I feel as though my posture and alignment are much better. I cannot thank you enough and will recommend this product to anyone seeking to alleviate pain or avoid serious injury down the line.
