The Spiuk Z16R are some of the comfiest shoes I've ever had the pleasure of wearing. Yes they could be stiffer and the dial could be more precise, but I was still able to achieve a perfect fit that will mean these shoes see plenty more miles this winter.
Multiple colour options
Could be stiffer
Dials can't be loosened in increments

This comfort is a little surprising given the adjustment systems used on the Spiuk Z16R shoes. Both the ratchet system on the top of the shoes and the Atop dial below it allow you to tighten the shoes in very small increments, but don’t offer this level of precision when you want to loosen them, and you have to release them completely. This could be a problem in hot conditions where your feet expand, creating pressure points which can only be relived by loosening your shoes.

However this was never the case with the Spiuk Z16R shoes. The fit is absolutely superb, sort of like a, well, glove, holding your foot snugly but not tightly, allowing for very impressive comfort and also helping with power transfer, with heel slip never being a problem.
Perhaps some of this comfort is down to the fact that polyamide and fiberglass sole is far from the stiffest on the market. This means a slight compromise when it comes to power transfer, and there are certainly some wasted watts when you jump out of the saddle for a sprint or climb. However if you’re not racing then this shouldn’t be a problem, and the Spiuk Z16R shoes will be a very capable club run companion.
