What amiable said
If there is one in Chi, maybe she can pick some up for you, at least then if they don't work out you are only out return shipping (I am going out on a limb and assuming the offer was there already for this service, haha)
FWIW I would not sacrifice style, color, etc - just to have THAT brand. If your heart is set on the brand, I would investigate the options available and see if it's worth it to me to either risk it and pay shipping and possibly return shipping.
Also you could start a thread on here to find out how their sizing is (or search archives). That could help reduce the need for returns, theoretically.
