Bought a pair of 510 shoes in the black and khaki.you can't tell the khaki color.it is a great black shoe. Stiff sole. Grip is good paired with my raceface chester pedals.
You have to make sure you foot lands on the pedal correctly because once the shoe is on the pedal you can't move you foot.
The sole of the shoe is stiff and I feel less pain in my feet after long rides.I used to get sore with my vans.felt like too much pressure on foot
The five tens are great.I already got them soaked after a rainy day and they stuck perfect to the pedals with no slip
