Taking my new Prolights out of the box, I was first struck by their weight-- or lack thereof. During my first ride, I was struck by their stiffness in sudden accelerations and climbs. For weight savings and power transfer, the Prolight SLX is pretty hard to beat.
The Prolight fit might not be right for everyone, even if you use the included Fit Kit's arch supports. The shoe's forefoot is a little snug-not like Sidi, but more narrow than Shimano, Specialized, and other brands. For point of reference, I wear 42s in most other brands, but need 42.5 for Giro's road and MTB lines.
Quality of materials and manufacture seems high. However, I have one concern about the top velcro strap. If you use the high or medium arch supports, your foot takes up so much shoe volume that you can only cinch down half the top velcro strap without overtightening. I've only riden about 25 hours in the Prolights, so perhaps more milage will compress the tongue padding to allow more strappage. So far, this isn't a problem, the heel cup holds my feet very securely. Rather, I'm more concerned about the velcro's longevity, since you can't replace it like a ratchet buckle.
The Prolight's rubber heel pads are a small but well-thought-out feature. They're much safer walking on tile or hardwood surfaces than my previous brand of shoes, which had had hard, slippery plastic bumpers.
Lastly, the Prolights come with shorter cleat bolts. Use them. The soles are so thin that standard cleat bolts might protrude uncomfortably into the balls of your feet.
Thank you for your feedback.
