Hey,
Each 1-2 years I have to fork out $100 for a pair of runners. (This is when they are marked down by at least 50%)
I run 30-50km per week.
I did try cheap nobrand runners and they started falling apart within about 4 months.
Even cheaper Brandnames (RRP less than 100) wear more faster than (RRP 150+) mark shoes.
How much do you pay for runners
It's over $100 for barefoot: http://barefootinc.com.au/vibram/
