I just bought Asics tennis-shoes from TWE. Shoes felt great in play, and the delivery and its tracking was good.
I personally recommend to try pair in a store before shopping online when changing brand.
Here is my sizes in sport shoes (as written in shoe):
Adidas: US 11 1/2, UK 11, FR 46, JP 295 (these are just a little too big but I'm between sizes with Adidas)
Nike: US 11, UK 10, EUR 45, CM 29
Asics: US 11, EURO 45, CM 28.5
Salomon: USA 11 1/2, UK 11, EUR 46, JAPAN 29.5
All these fit perfectly (exept Adidas, but they're still ok). In addition my walking shoes are size 44 with the brand Rieker.
