Boast Boat Shoe

I purchased this shoe in size 7.5 (my usual Jeffrey Campbell size. The white has light distressing and looks very similar to the very expensive Miu Miu Boat Shoe. I like the distressing. The inside suede is the underside of leather outside. The footbed has some foam cushioning, and there is no arch support. The shoe is made in China. The leather is buttery soft. The insole is not removable. The sole is rubber and very flexible. For me, this shoe is very comfortable. I would say it runs true to size. My foot measures a true USA -7M , 9.25 inches / 23.5cm in length. I have a fairly high instep. I wear most closed toe shoes in a USA-7.5M (37.5EU). For reference, I wear 37 Medium/Narrow in Birkenstocks, 7 in Tory Burch Miller Sandals, 7.5 in Tory Burch ballet flats. If I wanted to add arch support inserts , I would need to size up to an 8 in this shoe.
