NEW NEVER WORN!! When ordering a pair of Archies Flip Flops or Slides, we recommend you choose your normal running shoe size. Half Sizes: If you are normally a half size we recommend you size up to the nearest full size. Eg. If you are normally a size 7.5 we recommend ordering a size 8. Our specialised closed cell foam material is formulated to mold to the shape of your foot. Give them a day or two to wear in and you'll be in love with your Archies! Up to 2.2cm of orthotic support encourages optimal foot posture aiding whole body alignment. Perfect for people with Plantar Fasciitis. Your toes don't have to grip to keep your thongs on. Walk all day without overusing muscles and tendons in the feet. The strap can also be stretched to suit the width of your foot!
