I'm sure the distributors could answer this better, but I'll give it a go

The answer is numbers.
There just aren't enough climbers in SA to bring that many styles of shoe in.
Baring in mind you need to bring over a variety of sizes per model (not to mention 1/2 sizes).
One also needs to order a sizable quantity from the manufacturers (minimum order quantity) and to make it worth the while of the local distributors shipping costs.
Importing anything to SA is expensive (Customs / taxes).
The product has to travel a long distance to get here. In Europe or the US the distance traveled is less (when produced in that country or region of the world), even it it comes from China... they're bringing over larger quantities making it cheaper.
I reckon if you want something unique, speak to your local shop and ask if they can order something for you (expect to pay upfront)
Anyone remember the locally produced Mantra shoes
