I have micro spikes and they are great in some situations.
Never heard of these ones. Had a look, here's the link if anyone else wants to
http://hillsound.com/hillsound-product/trail-crampon/They look very similar, almost identical, to micro spikes. The plate with the spikes looks slightly more solid/heavier duty. Maybe the spikes a 1-2mm bigger.
Would be hard to choose between them. Wonder if there's a big weight difference?
Edit: check the weight. Size large for both:
Micro spikes 408g
Hillsound 480g
