1. Size: I usually 40 (sometimes 39) - have ordered 40 and they fit perfectly. 2. Color: pink - as seen on the image more gray with a little pink, but I did is right. 3. Insole: in such slippers, it is quite normal that this is to take out (so that the shoes will dry faster). We have in our family slippers of different. Manufacturers and it is always so. 4. General: shoes look good, material is comfortable to wear.
