Hi, I'm currently using brooks adrenalin gts 11 and they are coming to the end of there life. 

Ive been looking around for another pair as theses have been fantastic! 

All I can seam to find is the gts edition 12 or 13 are theses the same as the gts 11 just newer style/ edition??

 looking for 10.5. 

Any info would be great fully received
