The VM003-Lo Duo Green/Black has a slightly tighter top line measurement (where you stick your foot in) and yes, it also has all the nice hidden fea­tures as the other models, why change some­thing great? We love how this style came out, LRAB is all about fine-tuning and dimensions, just look at it and you will understand. The VM003 comes in both Lo and Hi versions, can­vas and suede.
