Size Chart
For sizes with a midpoint (e.g., 4.5, 5.5, etc.), it is recommended to size up to the next whole size (e.g., size up from 4.5 to 5). This ensures a comfortable fit, especially for footwear like boots or slippers, which may be worn with socks or need a bit of extra room.
This advice is particularly applicable if you're in doubt or between sizes, as a slightly larger fit is generally more forgiving than one that is too snug.
