poor quality of shoes

Last Friday 27/03/2015 my wife bought me shoes for a race i was performing on the 29/03/2015 for my birthday. she did her homework and was advised by takkie town boksburg the best shoe for the race performance and durability to reuse is the reebok mudder. I do alot of races and must say even the Mr price max range didn't fail as bad as the reebok and I wouldn't expect a R100 to out last a R650 shoe.after the race i noticed that the shoe is lifting from the sole. can clearly see that the glue has failed.i am outraged that after one short 10Km race i need to toss them in the trash. my whole family is runners and all wear your products. and have never had this problem before. But we are all appalled with the quality of shoes you have sold. Please can you advise me why this shoe has failed.i am outraged about this
