I hope that won't be too complicated I was follow somebody's link to Asics running shoes at Debenhams and came accros these ones.
First one is a famous GT 1000 model which at their site is described as "White mesh lace up trainers " but if you watch carefully you'll see model name on the pics(size 9 and 12 only available).
The other one is described as a Gel Pulse 5, but again if you look closer it's Gel Phoenix 6 (size 8-12 available), in my opinion any of these is a good shoe/model for the money..
I double checked this name/pics error with their C.S.D and my conclusions are correct.
All in all using code FV39:we get:
-Asics GT 1000 for £42.75 delivered or Collect in Store
-Asics Phoenix 6 for £40.50 delivered or Collect in Store
I think these are a good deals for a decent pairs of shoes
