The Naxo doesn have return springs, should I care?
In a word, no. Return springs pull your ski tail up to your heel while in touring mode. They may help control your ski tails while side stepping or doing kick turns, but add weight and resistance to your touring stride. Common wisdom holds that touring without return springs is more efficient. The lighter weight uphill biased bindings are sold without return springs (e.g., Dynafit and Silvretta Pure), and Naxo chooses to follow suit. The return springs on bindings such as the Fritschi models are easily removed. I suggest touring without them no matter what bindings you use.
