Go for Baxter Boots
http://site.baxterfootwear.com.au/
They are half the price of RM's and have the same durability
My first pair circa 1996 was A$70 and one re-tread circa 2007 A$60.
My second pair was A$140 circa 2007 bought at Lowes in Sydney.
The reason I moved to Baxter is that I met the family due to school connections in Sydney and am sure they would ship to HK.
But as Flexi intimates...the RM's may be better for the check rides..
