Mini - Thnaks for that link to the Stock Center, they seem to have a place here in Avellaneda as well, so I will check that out. On the web site, although they show Asics on their banner, when you look at the products, sadly they are not showing any

- but I live in hope.....
As for price comparators, I use Asics Gel Nimbus shoes, and in Ireland, the latest model will set you back around 140 euro's, which equates here to around 650/700 pesos. They are around the same price in dollars in the US (by the time you add the sales tax on the list price), ie US$140, somewhat cheaper than back home.
I have seen the Nimbus 10 (2008 model) here in a store, retailing at 735 peso, but seeing as the Nimbus 12 upgrade is out, I will try and souce those, probably have to go stateside to do it though, but I will try out that Stock centre.
As a running coach over th eyears, one thing I would say to any perspective runner, is make sure you get your feet checked, your gait analyzed, before you spend a lot of money on a pair of shoes. In running, the only real equipment you need to run is shoes, (OK, girls you need a very good sports bra too) and it is imperative that you get the right ones for you, your build, weight, gait etc., all play a part in shoe selection... No two people are the same, so I can't give advice on which shoe is right for "you", but don't go for a cheap solution if you are going to run - You will end up paying for it in the end.....
