Why 2 versions of Salomon Strive 14, GW + MN???

[psortti]

I am trying to understand why Salomon has two versions of the Strive 14 (picture from their web-site), Gripwalk (GW) + Multinorm (MN). What is the rationale? I.e. one version that only works for gripwalk and another version that is multinorm...?
What would be the rationale for buying the GW-version in that case? (For Strive 16 there is only one version for multinorm)...

I have scatched my head on this one too. Originally there wasn't going to be a MN version in the 16 (the first run was GW) but the athletes wanted MN, and I am guessing since they had the housing design alreay paid for, why not offer it as the 14. The MN is also about $30 more so unless you have an AT/MN sole (ISO 9523), stay with the GW.
