The ski shop said I have a normal heel size. They recommended the Tecnica 2 120HVl which does come in a 24.5 length. They felt this was a performance boot pretty much made for my foot size. Any tweaking would be minimal. After that they recommended Tecnica Cochise. They felt Tecnica as a line came with a higher arch volume overall which a shorter foot would benefit from
But no 24.5's in their stock and they said most of the boots for the year have shipped. They could ask rep to find some but if/when and how well it worked could be problematic, felt they could make it work but even those might require significant extra costs, custom foot beds, some boot modification, maybe even a new liner.
Previous boots were SureFoots, served me well for 5-7 years so I'm going custom again, going more local with and using a Strolz which is similar process to SureFoots with foam in liners, custom beds etc. Probably a bit more custom than SureFoot as Strolzs makes the boots and tries to size them as close as possible where Surefoot takes off the shelf brands and customizes them. Plus who you get in the SureFoot shop can be problematic. SureFoot will fix anything with no limits but really should not have to if done right and fixes require long trips to Sun Valley, Whistler or PC.
Expensive as SureFoot but 5-7 years of comfortable skiing, kind of a bargain.
