Hi guys - so I thought I'd give some feedback from the skates drama.
Me and my coach went through various tests to make sure the blades were balanced - as luck would have it, they were. So as I don't pronate or supinate - my stance is neutral, the blades were fitted neutrally it would seem, so all is well.
One thing I will say is that, my feet go extra cold after a short time on the ice and my ankles wobble a fair bit - but I think this is due to having to break them in a bit and tighten up the laces round the ankle more.
Anyway all is well besides that.
Ah, now there are reasons for the coldness and the wobble.
Edea's soles are very, very light and very, very thin. This means that the chill from the ice reaches your feet far more easily than it would through a thicker, more traditional soled boot. Best way to counter it is to wear thick neoprene boot covers that go underneath the sole of the boot, closing with velcro under there. I know Edea make them and probably others do too.
The wobbly ankle thing is because Edeas are not designed to fit snugly around the ankle. There's too much space there (for my liking, anyway). Some people get used to it, others never do. You can use the elastic things that Edea supply with the boots to hold the lacing more firmly. Tying the laces as tightly as possible in order to try to get the boots to wrap around the ankle is counterproductive as it will cause the boots to break down sooner.
So glad to find that the blade mounting is okay, though! Phew!
