So I guess based on Neil29's information, I can speculate the Ride Lasso Pro wide are for EEE widths as well.
@Neil29 I'd be grateful if you come back after trying them out on the snow and confirm you didn't have any pain that might have been caused due to width issues in the end.

SkA, I rode the lasso pro’s for about 3 hours and the TM-2s for about an hour. I wore both of them with new balance superfeet impact soles that are really thin and arch support is just right for me. Both of them felt snug with thicker insoles when trying to break them in at home. I rode with my new Rome Cleaver bindings that I was also trying to dial in.
The lasso pros are so easy to get on. The ankle support is controlled by the side boa and it’s so easy to get it snug and keep your ankle in place (no toe jam). The top boa controls the entire lace but doesn’t seem to tighten the footbed too tight. With the ankle support really tight, I didn’t feel like I had to over tighten the boot. I had no hot spots for the three hours with them. The interior of the liner is plush and comfortable (when I was working through insoles, I put the on without insoles and I could barely tell because it was so soft and cushy). The toe straps fit around the toe well and didn’t put any pressure through the boot. The heel strap felt good with these, but I think I’m going to adjust them higher on the ankle.
The TM-2s are a bit more bulky and much more involved to get on. The ankle drawstrings over the liner is standard but I can never get it tight enough to make my ankle feel secure in the boot. Then the calf strap has to be tightened and then the two boas. It’a more than twice the time and I don’t feel as secure in the boot. After wearing the Lasso’s the interior of the TM-2’s liners couldn’t compare.When tightening the toe straps, I could actually feel pressure in my outer two toes from the straps. The heal strap was also creating a weird pressure point that wasn’t nearly as bad with the lasso’s (I’m pretty sure I could avoid this if I adjust the straps higher). The TM-2 are also about a little shorter, but it didn’t cause too much additional pressure at the top of the toes. After an hour with the TM-2, I was a bit more uncomfortable than when I finished with the lasso’s. They are good boots and if I didn’t try the lasso pros I would be happy with the TM-2s.
i hope that helps, I may try the TM-2s one more time, but I’ll probably sell them.
