Fizik K1 Donna Tri Shoe
Triathlons require specific gear, and the struggle at T1 is a perfect example of when having the proper equipment comes to light. T1 is a popular source of videos that 'one sporters' like to snicker at due to the chaos caused by the incredible coordination and balance required to put on cycling shoes while mounting the bicycle. Fi'zi:k's Italian, handmade K1 Donna Shoes are designed to ease this burden.
At the uppers, Fi'zi:k used a material that we don't see in use very often with cycling shoes -- neoprene. We know what you're thinking, how hot is it inside these shoes? The answer? Not hot at all. In fact, aside from the ample perforation and ventilation panels, this material is highly breathable. It was used over the Fi'zi:k-standard, Microtex, for its water-resistance and ease-of-entry with wet feet. So, your transition from sea to land won't be slippery.
For fit, Fi'zi:k incorporated a one-strap closure system, mated with a 'burrito-wrap' upper. What does this mean? Well, the K1 features an opening that runs over nearly the entire top of the shoe. The burrito analogy is drawn from the K1's upper construction where one layer of the upper wraps over the other. This allows you to really dial in the volume of the shoe, whether it be for training or on-the-fly during a race. For your T1 transitions, the two-strap closure system is a breeze. The large top strap opens away from the drivetrain to allow a quick and seamless securing of the shoe. As for the bottom strap, you'll find that this is used less for transitions, and more left alone once you've established your desired volume and fit. However, the gripper tabs placement on the strap simplifies any adjustments that you might need to make from the saddle. To really speed up T1, Sidi has also included a durable pull-tab at the heel.Technical Specs:
