It's a typo.
In other news that you guys might be interested in, we have been cleared to do a set for Styleforum for the FW/Holiday season:
1) A chelsea or side zip boot
2) A rugged boot - a service boot with 5 eyelets - yes, the 1940s service boot is apparently back.
3) Either the long awaited Echo boot, if we can figure it out in time, or another cool, more streetwear like, boot.
Nice! Zip boot and I would be in.
