Sidi Genius 10 Mega Road Shoes (Black/Grey) (46.5) (Wide)
It's great to find cycling shoes for my wide feet. I did not realize it until recently, but my previous shoes caused a painful ingrown toenail on my big toe. These shoes are the perfect width, and I feel no more pressure on that toe. My feet are pretty flat, so I added a supplemental insole below the shaped insole to pad it out a little bit. The Tecno 3 closure dials will take some getting used to after years of Boa, but I can live with that. The tongue is thin and doesn't really bend all that well, so I may cut the notches they come with to better fit the curve to my ankle.

Sidi Genius 10 Mega Road Shoes (Black/Grey) (48) (Wide)
I purchased the 48 mega because of my wide feet and high instep but, unfortunately they were too big. I returned the shoes and ordered the the 48 and they fit perfectly to my feet. The return was hassle free and I was refunded the money the day Performance received the shoes. Overall I give Performance a 10 out of 10 for customer service and fast shipping. Would definitely buy from them again. As for the shoes, love them!

I am very pleased with my Sidi riding shoes. The fit is just right and the are comfortable. I have been on two 30+ mile rides without any discomfort. The ordering process was easy and shipment was extremely prompt. My previous pair of Sidi shoes lasted 9 years and apparently 20,000 miles and hopefully these will as well. My last pair had the ratchet strap at the top and Velcro straps across the middle. The Velcro wore out on the old shoes. This pair has the cord straps in both places. Hopefully they will be as durable.

How to Measure for Size:

  • Measure length of foot in centimeters from heel to big toe
  • If measurement falls between two sizes, Sidi suggests choosing the larger of the two sizes and adjusting fit with insoles
