Yeah they're definitely "aggressive fit"... I had them fitted by a chap in Edinburgh climbing centre so alledgedly they're a good fit? I'll give them another few tries before I pack them in and go again...
There's this sales chap at my local gym who's always telling casuals to buy their shoes two sizes too small. What works for them doesn't work for everyone! But you might be ok, Skwama's seem to stretch at least half a size over time
'Agonising' sounds like they're way too small
