Those minicrampons are very good for walking in snowy conditions; I have some 'proper' crampons and some of these mini-ones, and I find that the latter are so much easier to put on and take off, even with cold fingers (though, mind you, I must admit that my 'proper' crampons are very old ? I daresay modern ones have much better straps). For ordinary walking on icy ground they're excellent.
