You don't want to lean a bike through turns on loose aggregate in any circumstances, but ive found there is little room for error with these tires. In straight line conditions on pavement, with no leaning, the traction is of no concern.
Unless you ride with a really weird pressure, the rubber has contact in curves. The studs are not that long. I also assume that in winter conditions you don't ride fast enough to require a 45° lean angle on a bike path or road. Un-studded tires for hybrids/commuters in general are not optimized for riding like in a race or so.
