My Husband Has Plantar Fasciitis And Has Orthotic Insoles And

My husband has plantar fasciitis and has orthotic insoles and orthotic shoes. Wore them in the house for two days and felt good so started wearing them to work with wool socks as he was told to keep his feet warm. He works in a warehouse with cement floors and does a lot of walking. First evening he came home and the foot without planter fasciitis the big toe has two blisters on top and had swollen and red. He's still trying to work with these shoes and is now limping. He comes home and soaks them in warm water and salt and then puts polysporine on it. It's been five days now and still the same.
