Running-shoes: Status

Today I'm using three different running shoes:

1. Mizuno Wave Ronin:
Purchased: 8.4.10 at "Løplabbet" in Oslo
Main area for use is competitions.
Total km: 202

2. Puma Concinnity:
Purchased: 30.4.10 at "Løplabbet" in Oslo
Main area for use is training off-trail
Total km: 223

3. Montrail Masochist:
Purchased: 14.5.10 at "Løplabbet" in Oslo
Main area for use is training on-trail.
Total km: 308

Right now I've decided to use the shoe from Mizuno only as I suspect that the other shoes are the reason for my recent problems with my knee's.
