The Durolux ($849) comes in two different versions, one with a solid crown that's billed as 'Extra Strong', and one with a hollow crown to save some weight.
The Trailcross is lightweight and very well ventilated. It's also designed to drain and dry quickly, ideal for those summer rides that involve stream crossings.
Five Ten's Trailcross Pro shoe ($200) flew under my radar - I didn't even know it existed until today, but it's an intriguing option. It uses a Boa dial and a velcro strap to adjust the fit, with a mid top height and a neoprene gaiter to keep out trail debris.
