Who has insulated winter shoes?

[lph]

I have Shimano winter shoes, SH W101. They have a solid waterproof sole, a neoprene cuff and a roomy foot box for my short fat feet . They aren't superwarm, but I got them on sale and they're quite adequate. I've replaced the insole with one in wool felt, and wear medium-weight wool socks in them.

I use them for commuting, 45-90 min each ride. They're fine on their own down to about -4 C (25F), below that or if it's raining I add Gore-tex booties over. With booties they're good down to -8-10 C (14-18F). I'll ride down to about -15 C (5F) but then just short rides, 45-50 min.

I'm lusting for a pair of Lake winter shoes, so I'm saving up for when these die

eta: I think I mean shoe covers, not booties. Full Gore-tex covering, but with an open sole with just a band to keep them in place.
