New BalanceMen's Mx877 Cardio Comfort Cross Trainer

Can someone tell me if this shoe has a wide (or deep) toe box? My toes sures can use the extra room. Thanks.

I ordered walking shoe 574. Is 877 the same? If not, why the change?

Wht color are the soles? White or light grey? I can't tell from the pictures. Thanks

The title says 877, but the picture shows 847v3? Which is correct?
