Shoe Repair

Several years ago I posted about repairing massive separations in my approach shoes using Locktite PL S-30, a Home Depot caulking product with great adhesion and flexibility. I wire brushed it, over-filled it with the polyurethane, and removed the excess with a grinder. Much abuse later, it's hanging in there. I credit the higher flexibility better moving with the shoe than the traditional Barge Cement.


A few months ago I decided to repair the rand on my favorite rock shoes, which had start flapping years before but had become extensive over time. A little more complicated this time, involving masking tape and wax paper, but so far so good. Trust me, I've treated them badly.


Other polyurethane adhesives, available at Home Depot well worth consideration are 3M 5200 (white, less flexible) and Locktite Marine (white or black, slightly stronger than PL S-30/40).

Pretty amazing stuff. I'm finishing an article testing strength of about 20 marine caulks and an article on repairing canvas and sails without sewing. This stuff can be amazing repairing canvas, particularity if sandwiched between layers.

It's All About the Feet

Ask a climber what gear is most important--the rope, the pitons, the pack--and they will always answer the shoes. You weight is on your feet and your control of that contact point, not strong arms, gets you up the crag.

With ice it's little different, but shoes are now covered with spikes in the form of crampons, and the fingers replaced by ice axes. While the axes are in your hand, in your face , and most immediate, it is still the feet that provide the base. If the feet sketch about, neither security nor style are possible. And so shoe failures are a major problem. I could just buy new ones, but plopping down $500 for something I will use a few times in a good year and for only so many years into the future is bitter, and I like many things about the ones I have.

 Heel Lift. Traditional rubber strap lacing does a fair job of holding the crampon to the but, but with less than rigid boots and vertical ice,he heels can lift an inch or more.
Enter some non standard lacing, or rather something similar to the new heel cup bindings. By threading the ankle wrap through the heel strap, the hold down force is increased about 30%. A new twist on old tech.

I like the Balatoros for their light weight, easy hiking, and agility on ice, but the same flexible ankles that make them fun, make them tough to front point for long periods. Previously, my Trezeta Sherpas did the job, but they suffered from total separation during a Great Falls ice climbing trip a few weeks ago.

But with bulk removal of rotted foam rubber and massive applications of polyurethane, perhaps they will have new life. But I'm not holding my breath. Perhaps they can finish the season, perhaps a few more. Ugly too, though that probably helps.

More Ice

White Oak Canyon, this time. Chris and Drew.

The original destination for the day's expedition was Overall Run, but we elected to approach from
Skyline drive and the Park Service elected to close a drive due to icy conditions (1-inch of snowfall). Faced with a barricade, we retreated and drove to White Oak, where predictably good conditions resulted in 3 leads, numerous top ropes, and tired bodies.

Chris honed gear management leading WI 2 on the lower falls. We both bouldered on the cauliflowered base, marveling at the flow, the lace-like structure others travel to view and photograph, but for some reason we are drawn to scale.

Further up the canyon we found the south side to be unstable and thinner than expected. We talked about possibility, then something substantial fell and better judgment prevailed.

The grotto was nice and cold, though and the steep walls nearer the falls provides some short but stiff leads and top roping. And quiet. No company other than the thunk of ax and the crunch of front points.

Nice.

Ice



Although this latest arctic blast has my boat securely frozen in her slip...

Virginia takes on a different aspect, mid-winter.


(50 yards north of the Microdome, Great Falls, Virginia)

Drippy places, unappealing to summer rock climbers, become a playground...


... and thin ice holds a special challenge. (Left of Gorky Park, Great Falls, Virgina)

 




Classic 60s crampons, making the grade; My fancy high tech boots exploded the week before, but old school hangs in there.
