I stumbled on Aetrex in GSP (2nd fl, next to Apple Store) while I was looking for a pair of good quality shoe soles. As I asked about their four types of soles, I found out about their free feet scan, and found out some surprising information about my stance and my feet, ie difference in arch height, width, length and pressure point difference. Shaun was excellent and expert at foot science, gave me full details on how the soles can help me with improving and stabilizing the arch and pressure points. I bought one pair to try it out. After using it for 3 weeks, I found the soles to be effective and high quality. I used the pair with every shoe pair I wore everyday. After my positive experience, I went back to the store 3 weeks later to redeem the B3G1 offer, by purchasing 2 more pair, getting the 4th one for free. Since they didn't have my pair on stock, they ordered free shipping to my home. If you have doubts or issues with your feet or looking for high quality soles, I recommend this shop. Also you get the feet scan for free, no purchase required. read more
