The easiest way is to order 4-5 pairs you want to try to your nearest Evans on your credit card, try them on and get refunded on the ones you don’t want.
But really it’s 99.9% about the fit. It doesn’t matter if a reviewer marked them down for being less stiff than X, or not as ventilated as Y, if X and Y don’t fit your feet then they’re useless. Hence I have R171’s, they lack ventilation in summer, lack insulation in winter, are fragile (I’ve cracked the sole walking in them), velcro is mehhh, and the ratchet isn’t as nice as the SIDI ones or BOA, and they were £170 I think. But shimano wide fit are the only ones that suit me, and they only do one top end shoe, and one really basic one in that size.
Ideally i’d buy from one of my LBS’s but neither of them stock footwear
Wonder why.
