Can you check the sizing on the lower shell, Raichles usually have a size range for the upper cuff and then below that on the lower shell is another size which is for the lower. Is this the 29-30 one, I think it is usually only 0.5 size range. My set show 28-28.5.
Anyway can you also look at shipping to Calgary, T2M 3W5 by postal service, no big hurry on delivery.
