Shoes are the vehicle in which the orthotics are allowed to do their job. Loafers for a start are completely inapropriate as they have no kind of fastening to keep the foot help down onto the orthotic,. the shoes should also be fitted by a specialist fitter to make sure the foot is positioned correctly as the orthotic will change the way the shoes will fit. any footwear should be supportive but especially so with orthotics as it will keep the ankle in line and help prevent any excess rolling over the edge of the orthotic. ideally you are looking at a laced piece of footwear that gives adequate room for the foot and orthotic to function properly. It is still advised to get specialist footwear advice from a specialist fitter.
