At 250 lbs I blow thru the old korkers i mean i would loose 3 spikes in the first night.i have found the gladiator sandals buy hodgeman hold up alot better It all depends on the terrain.them boots from LL bean Nebe wheres are nice in the head size bolders an the sandstone like granite of RI.They have a lower profile so u don't roll as much when u walk. on large granite jetty rocks them things can be dangerous.As well as the screw stud replacements.no good on big wet or even worse DRY jetty rock.U need the bite of carbide to keep ya from slipping.So i reccomend the galdiators an some kinda boot type studded shoe.I have a pair of chota's i'm gonna rig em up wit these.
