Comfort wins the day.

Diadora has learned to walk a fine line between comfort, efficiency, and weight in its cycling shoes. For the Speed Vortex Cycling Shoes, the Italian manufacturer opts for a slightly heavier sole (by 10 grams per pair) that incorporates the same NET breathing technology found in the line-topping Vortex Pro. The soles are constructed of a synthetic mesh and breathable, impermeable membrane that increase the soles' transpiration capacity without letting moisture, mud, and other external elements in.

The Speed Vortex Shoes also feature the Vortex Pro's Suprell-Tech Morpho AM Cage technology. The shoes stay tight against your feet without restricting circulation. Inside the upper, the EVA insert is perforated to further promote breathability and removable, so you can optimize your level of arch support to your own foot shape. The molded, abrasion-resistant Duratech heel cup is updated with a griping texture to keep your foot from slipping, but is also removable if your feet demand it.

The closure system incorporates a Boa wire system — almost mandatory for quality cycling shoes today — and a hook-and-loop strap. The Boa wire lets you fine-tune the fit across the top of your foot, where the most pressure is applied to the upper, and the hook-and-loop strap lets you modulate the pressure over your metatarsal area. Anyone who's experienced crippling hot spots in the toe box will appreciate this variable approach, as it lets you customize the shoe's fit for firm support and spacious comfort at the same time.

It did not fit right

  • Familiarity: I returned this product before using it
  • Fit: True to size
  • Size Bought: 41.5

This is not my first diadora cycling shoe, I had 2 pairs before this one and this one had a weird fit. The boa knob felt quite uncomfortable, felt like a hard rock between the shoe and the knob. I returned it and got a different shoe.
