Getting better ;)
Sorry about the lack of sizing on our site, we're looking at revising it again soon.
PLEASE use the EU portion of this sizing chart:
Additionally, we can custom size our gloves with a hand tracing sent via email if necessary. Since custom sizing is new to us, we'll ship the standard size and customize it if the "stock" pair doesn't fit properly.
You should only be concerned with custom sizing if you have typically different hand features; long fingers, wide hands, etc...
