This one no where near as strong. I bought a size 7 for my 3 year old. Consiglio vivamente il prodotto. Its a $74 mouse, I expect more of this. I use mine all the time and have had years of experience using these before I got one for my home shop. Get same size you wear in shoes and should be good. We went on vacation to California recently, walking all through Huntington Library and Gardens, Bowers Museum, and Disneyland, and his feet didnt hurt him at all wearing these sandals. No break-in time necessary; they were comfortable from the first moment I put them on. There isn’t much in the way of support for his plantar fasciitis or foot in general, but we also didn’t buy the slippers for this purpose. These daisie sandals are adorable.
