Comfortable insole, failry light boot for such a solid construction. Smooth leather but not overly flexible (ie it is a hard leather) so I guess it will retain its shape well. I have only worn them indoors just to try them on so far! Overall quite pleased with them, but maybe prefer a softer leather around the opening of the boot so that it feels more comfortable-especially if you're wearing stockings or shorter socks that don't go above the boot height.
