The Northwave Typhoon Evos are among a growing number of top tier shoes to eschew the traditional 2 straps + ratchet configuration, and go with 3 straps only. Whilst at first this may seem like a step backwards, the benefits in terms of weight and simplicity are worth considering.
The Bontrager RXXXL Limited Edition Road Shoes are an extremely lightweight race day option with a decent amount of comfort.
Bontrager call this a 'ZeroXS' design and you can see why. They've pruned everything right down to the minimum. It's all about those incremental gains (we might have to retire that phrase soon on the basis that it's getting old and knackered).
Prolight SLX: with a name like that you can pretty much guess what Giro's top end road shoes are all about – lightness and a pro-level performance. At just 205g per shoe (size 42), the Prolight's are some of the lightest on the market thanks to a lack of mechanical closures, a smattering of titanium bling bits and an ultrathin Easton EC90SLX carbon sole.
