Fitting the Dynafit TLT6

   This is my first time fitting a boot beyond molding the liner. The fitting took some trial and error but I was finally able to get the boots dialed in.

   I started with a one finger shell fit, as in with my weighted foot in the boot shell (no liner), with my toes touching the front of the boot, I was able to fit one finger (maybe a touch more) between my heel and the boot heel. Length felt ok initially, but obvious I needed some more room in the toe box. To solve this I put a tennis ball in the foot box, heated the foot box with a heat gun until it was too hot to touch then used a C clamp to blow out the toe box a bit, being careful as to how much area I was taking out above the foot. The idea with the tennis ball is to prevent any collapsing and to keep some sort of natural curvature as opposed to a flat spot.

   The C clamp method gave me a little room, but after one tour it was painfully obvious it wasn’t enough and I also realized I could use just a tiny bit of length. 

   I messed around with the idea of trying to fabricate a punch, but didn’t really want to spend that much time. I ended up making a wood form of my feet since it was quick and easy. The problem area for me is the toe box, so I traced my foot on some cardboard and used that template to carve out my wood form.

Crude, I know, but it did the trick.

I used some threaded rod  and a few bolts to push the form forward, towards the toe from the heel.

   I put the form in the toe box as far as I could, then used a heat gun to heat the toe box while tightening the nut to inch the form forward. It’s handy to keep the cardboard template close to see approximately where the “toes” of the form are at. After the heating and stretching I put the boot outside to cool down and retain the form.

   It worked out real well. I was able to get the extra length and width I needed in one go.
