In reply to UKC/UKH Gear:
I bought a pair of Seracs, the clip version, just before Xmas. Used them twice so far, once with "B3" climbing boots - in this case my now elderly Trango Extremes. We soloed up Crib Lem, II, then did another route we reckoned to be III,4 that day and the Seracs were great. I then wore them again a few days later with these B1/maybe 2 boots https://www.ukclimbing.com/gear/footwear/mountain_boots/mammut_kento_advanc... and did Crowden Clough (Winter) (II), with a reasonable amount of ice in it. Again the Seracs were just perfect. The secondary points are nicely angled for ice, but they work just fine on mixed too. I reckon they are really classic and classy climbing crampons if you want them to be, I'm addition to be fine for walking, but maybe more than you need for just walking.
