I bought these in May 2013 from Sports Direct, who I believe also market under the Karrimor company name. I have since found out that the once great Karrimor brand was bought by Sports Direct a few years ago when the company went bust. They now manufacture inferior products with the Karrimor label.
Delivery was quick and the shoes themselves were very comfortable. One of the lace loops broke as soon as I pulled the laces tight the first time, but a bit of needle and thread sorted that out quicker than sending the product back.
The shoes were great, for about 3 months. By then the soles were getting quite thin. A month later and they were worn completely through in places and so thin elsewhere that it was painful to use them.
I walk a lot, and the 3 months probably covered about 350 miles on woodland and heathland walks (i.e. not scrambling over rocks!). If these were just cheap trainer shoes from Primark, I'd have probably been ok with them only lasting 3-4 months. But they are marketed as walking shoes, so I would expect much more life than this. Other shoes/boots I have bought for a similar price have lasted a year or more.
I did try to ask Sports Direct if this was a normal lifetime for this shoe, and to see if they would refund or replace them under the sale of goods act (not being fit for purpose). They were very unhelpful. If I'd paid more then I would pursue it further but I'll just write it off as a bad buying decision. I've since bought some (more expensive) Merrels from another company, and so far they are going well.
