Footjoy Dryjoys - Casual (spikeless) okay for winter use?

Following on from my Sealskinz socks question, are the above shoes good in winter being spikeless?

I'm not really keen on the look of the more traditional style with changeable spikes.

2 completely separate issues seem to be involved here from the responses so far

1. waterproof - that's an issue for the shoe specification (and whether it meets it!) and isn't really a winter factor either; it can be very wet at any time!)
2. grip. Some molded soles are actually better than spiked models, some are useless. It really comes down to the specific model. To a degree this also applies to cleats/soft spikes as well. I don't have the FJ DJ streets (I have 2 pairs of the cleated model that are excellent) but I have both Eco streets and Stuburt molded soled shoes and the former are better than cleats - the latter are useless as soon as the grass even gets damp!

These comments apply to grassed surfaces and grip to that grass - if you have mud, or banks where the grass surface will break away/slide under load then you need crampons to be safe ie something gripping into the lower layers of the ground, but that is a completely different issue!
