Vibram FiveFingers Men's V 2.0 Trail Running Shoe

If I see someone wearing these can I beat them?

I have an old pair of 5 fingers.. in between the toes wore out.. is that solved here? .... Also , im 10.5, what size is suggested for these?

How wide are these shoes, can I order a wider size?

I have a pair of five fingers that are about 7 or 8 years old and they are a size 42. What size should I get in this model?
