How should road cycling shoes fit?

Road shoes should fit snugly without pressure points. Your toes should barely touch the front of the shoe when standing, with no pinching or squeezing across the forefoot. The heel should be locked in place with no lift when you pull up. There should be even pressure across the top of your foot from the closure system. Remember that feet swell during riding, so a shoe that feels perfect in the shop may feel tight after an hour—err slightly toward more room if between sizes.
