We Cross for many years. At our "old" (unfortunately, this year too small), the numbers are 10/11. In PC this size is not to be found. So I have the size 28/29 (which also actually corresponds to its current size) ordered - because Crocs actually turn out always great and wide. Now came "the new" with the size specification 10/11: -. (!!! Ergo equivalent 10/11 size 28/29 This size we did already and is too small but presumably is then 30/31 too.. great !? why we must now make do this year without Crocs Therefore, two points off Otherwise, the best summer shoes for kids -.. slip on quickly and easily, wash under the tap and to customize Jibbitz individually for every taste! Too bad that the size when ordering was not recognizable! Please change the !!!
