@nesneros, ask your bootfitter to describe the difference between custom made footbeds and custom made orthotics. Ask why you are being steered towards orthotics instead of custom-made footbeds. In my world, orthotics are hard and inflexible, while custom made footbeds are somewhat flexible. Some feet need the orthotics, while other skiers need footbeds and definitely should not have orthotics. There is no reliable and verifiable research confirming which skiers need which. The philosophical approach of the bootfitter will determine what he/she suggests to a skier.
Orthotics (in my world, here in New England) begin with a cast made of the foot using plaster gauze. The bootfitter forms the cast around the skier's foot, while the skier is in the shop. That cast is used to make a plaster mold of the foot. That cast is sent out to someone elsewhere to make a supportive "orthotic" that matches the foot. It will be rigid, and thus will keep the foot from collapsing.
Custom made footbeds, on the other hand, start in the shop with your foot being pressed down onto a responsive surface that will conform to the bottom of the foot. You sit and press your foot onto a plate that holds a soft, responsive surface. The bootfitter takes that plate with the shape of each foot down to his boot-fitter-cave and makes the actual footbeds using some kind of bootfitter magic. You sit around waiting. After a while the bootfitter brings back your boots with the footbeds in them. You try them on to check the feel. That day you will leave the shop with footbeds inside your boots. If you decid to get orthotics instead, you will have to wait for the orthotics for a week or so while they are being formed elsewhere and mailed back.
These processes may differ bootfitter to bootfitter. The big difference in the final products is that the orthotics are rigid, while the footbeds are somewhat flexible. The amount of give footbeds have can be manipulated by the bootfitter in the shop. There is no "give" in orthotics.
I've used both. The reason I was eventually sold orthotics had to do with the excessive hypermobility of my feet, along with problematic dysfunctions resulting from that mobility.
Maybe others here will tell you about their experiences.
Hence “liquidfeet”, I presume.
This is probably my fault, I’ve been using the terms interchangeably, but by your definition this is definitely a custom footbed. He took the mold but is working on them while we wait for their fall shipment of boots. The process of taking the initial impression was identical to the forming of my Sidas custom winter pros, so I was curious to know what the difference is. I guess I will find out.
I’ve also had a few plaster cast orthotics, but it has been probably twenty years since the last ones when I was a teen. I thought perhaps the tech had evolved with these new thermoplastics.
