on a recent trip i forgot to change over the heel bails on my crampons and found the straps too short for my double boots. no problem, i got the extra length by threading in 2 of the simple straps off my Cilogear worksack. true, any pack could have provided this, but from a Cilogear pack there was no need to fiddle or cut them off.
note the broken yellow bail and the metal D ring hooked round the tooth of the crampon
more telling tho, after a few hours into a 2 day trip i broke the binding (another story) and a 3rd simple strap saved the day, jury rigging for another 20hrs of climbing. the retention strap is one thing, but actually binding the hardest wearing part of a crampon to a boot for 20hrs of loaded climbing on rock and ice is several magnitudes up the scale. not only did it not need further adjusting, but aside from minor deformation there was no damage to the straps metal D ring.
makes me wonder what else simple straps can be used for…
