The only drawback to the Speed Nose on the Dynafit TLT7 boots is that it doesn’t support crampons with automatic toe bails (the simple wire that wraps around the toe welt). The solution is to get a semi-automatic crampon, or modify your auto with this adapter. Remove the simple wire bail and replace it with this gizmo that fits into the toe fittings and securely wraps over the top of the boots. The mod is rated at easy to moderate difficulty, depending on whether the bail on your crampons is designed to be removed. Enjoy all the benefits of Speed Noses and automatic crampons attachments with the TLT7 Crampon Adapters. Sold in pairs.
NOTE: This adapter is not compatible with the Hoji Pro Tour boots. Some smaller sizes may work but it's not a design feature. It does work with the TLT8 and PDG 2 which use the same shell.
Questions & Reviews
I have the Dynafit TLT8 Carbonio boots and after a season of using a semi-automatic crampon, I decided to give this a shot. I had read a few other experiences that were less than positive so I went in with low expectations. Next, I decided to mount these to a set of Petzl Leopard crampons which are not Dynafit's list of compatible crampons (setting myself up for success!).
So, we have a poorly reviewed product mated to a crampon not specified as compatible. Well, I am a professional bicycle mechanic and I'd like to think I'm pretty handy so here goes...
Honestly? This set up was a snap. I tinkered with the fit, put the toe bails on loosely and got it dialed. I took the bolts off, added loctite to all the threads and carbon paste between the flat part of the toe bail and the flat part of the crampon. Tightened to 6nm and it is REALLY solid. A hard enough impact would move the bail but it might bend the aluminum first.
After getting the toe end perfect, I adjusted the coil length to get the right tension and good to go. The fit is tight, everything seems very secure and even if the bail were to dip down, I don't think it would affect the retention of the boot in any way. I'm stoked, will report back after I've kicked the shit out of these for a few months but all in all; this is a good solution for boots without a toe welt.
Better to just buy a pair of new semi-auto crampons that you'll be confident will stay on your feet in a high consequence scenario. I'm honestly surprised skimo sells these given how janky they are.

The TLT8 has the same lower shell shape as the TLT7, so this adapter will work for the TLT8 Expedition CR as well!
FYI I used the adapter with a size 28.5 boot and BD sabertooth crampons.
