Hi and welcome to SaleHoo adb-trading-co :) Nice to have to have you with us!
First and foremost if you are looking for authentic brand name shoes and trainers then Chinese sites such as saveintrade.com should not be part of your list. Your risk of buying counterfeit items is quite high so best to refrain.
As the for Saveintrade.com I highly doubt their products are genuine :) They claim to accept PayPal the PayPal verified logo is not even on their site. Plus their site is relatively new, it was created just last March 11, 2011. It is best to deal with well established sites or those that have been online for at least 2 years.
