If unsure of which one to go with then definitely go with the standard arch support model. The standard arch support model contains legitimate orthotic / arch support, is super comfortable and almost every person absolutely loves and raves about this thong! You can then consider going for the high support model at another stage once your feet are used to having the support.
Regardless of which model you choose, do not stress, it’s not a big decision! Both models have substantial orthotic / arch support and it is highly likely you will be happy with whatever you choose! In the unlikely event that you choose a model and are not 100% satisfied, simply post the thongs back to us in new / unworn condition and we will happily send you a replacement pair in the other model free of charge. To prevent misuse of this offer, return postage of the original pair is at the expense of the customer, but we will happily pay for the postage on the replacement pair.
