These ice claws have worked really well during this icy northeast winter
I put them on 2 different winter boots  the heel band around the wide toe of the boots
I found them stable and lost one while trekking in deep snow but found it fast!
Otherwise have been security on glare ice and snow covered icy slopes and flat ground

Price was decent.  Although the Velcro straps were too long I chose to not cut them
That said great ice grippers
