Having spoken to the guy bought them I went for these, the bloke himself has done spiking up for a lot of the Indian cricketers showing me pictures of Tendulkar, Dhoni and Kohli all wearing trainers they have had spiked up by him. From the photos he has done a good job and they look sturdy! Will be swapping out the black laces for white!
In fact looking on his facebook, it looks like hes got multiple sizes of Asics spiked and ready to go. They all look like the Asics that are currently on sale in the Asics Warehouse. Overall it cost me £75 inc delivery for the boots which i think is a pretty good deal. Good enough that if they do break its not a bank breaker to buy a new pair
