i wore my 3G tour ultra's today for the first time. i can't get used to how light these shoes are.....and yet there build quality and overall construction seem very solid and firm. they felt broken-in right from the get go. i used my usual set-up of the deerskin leather sole and the flat hard rubber heel. perfect slide ! what a pair of shoes.....they look great, they slide great, and they're lightweight and comfortable.....what more could you ask for in a bowling shoe. thanks to phil, eric, and everybody at 900 Global.
