It doesn't feel as if they are rubbing (no hot spots or blisters), more of a bruised feeling, as though they are simply way too tight. They aren't, I don't think - I can easily stick a finger down the boot-top and slide it most of the way around - but that's how it feels.
Yes, that's it, the leg just above the ankle bone. The ankle bone itself is all right in these shoes (though not in most pairs I tried on.) After a long walk my legs above the boot do look swollen, legs at the top part of the boot are purply red 3/4 of the way around (everywhere except the front) and painful to touch. It takes about three days for the tenderness to subside to where I'd dare put the boots back on.
I know my fingers swell up during a long walk so no surprise that my calves would too. Maybe I just need to stop every hour or so and loosen the shoes a bit?
Yesterday was the longest we've done for a while: 3.5 'Swiss hours' (we did it in 5.5, my dawdling skills are legendary) above the Walensee. Au-Quinten-Weesen if you're familiar with the region. Steep 300m ascent, ground uneven (most 'steps' are actually rocks or tree roots) and then a gentle downhill slope the rest of the way. It was worth it but ohhh my ankles.
And you can scratch the bit above where I said they don't actually look bruised the next day, this time they are.
A more 'normal' walk up till now has been about two hours, on more or less flat ground, e.g. start at Schwanden and walk down the Linth as far as we care to. Trying to branch out from that a little bit this summer though.
When I first moved here my colleagues would invite me out on some of their weekend day trips ("there's a cog railway, you can catch that up to the second-to-last stop and then walk the last 300m with us.") I invariably managed to twist an ankle on the downhill stretch, and finally somebody suggested I "might want to consider" buying some proper shoes. It's worked a treat, I haven't twisted an ankle since but these 'bruises' or whatever they are are killing me.
It's the whole way around the ankle (I keep saying 'ankle' but as Longbyt says, actually the leg just above the ankle)... if it were ligaments wouldn't I be feeling it just in one place, front or back or wherever? Dunno.
I'll get some hiking socks and report back. Have been walking in thin gym socks on the principle that added thickness = more pressure on poor ankles. Maybe more pressure is what I need though? Doesn't make sense but I'll give it a go.
