Well Sonia, I can assure you, even us guys can never have too many shoes...I went through my shoe collection the other day (Imelda Marcos would have been shocked!

)...there were slippers, high-tops, lace-ups, velcros, trad shoes, sport-shoes and sad to say most were well past their prime...some downright nasty (smell-wise and condtion-wise). I have had to bite the bullet and chuck three pairs recently...my La Sportiva Cobra slippers (who never recovered from Thailand- that place destroys shoes and gives THE worst foot-funk!

) also my super comfy old school Trango Carats which sheared apart at the toe last outing in the G... and finally my high-top La Sportive Enduro's, the holes were just bigger than anyone would fix. So looking about to replace them and get another pair resoled (La Sportiva Testarossas) I have picked up a pair of La Sportiva Venoms. (You can tell which brand fits my fat foot best). For 140,000won I got a pair of these babies, a kilo of chalk and a pair of leather belay/ rap gloves...so I think it was a fair bargain. Funny thing is though, in all my different shoes (I can remember owning some 12 or 13 pairs) I've never found consistent sizing!
In the same brand sizes vary so much. My Testarossas are a 39.5, my venoms are 40.5 and the old Cobras were a 41!
I have noticed that overall though, the comfort of rock shoes has really improved. When I first started climbing, it was a session in torture, now even the tighest, most radically twisted shape shoes can be really comfy! I think the lesson is to really pay attenion to size and fit. Find out what works for you and ignore what others recommend if it isn't feeling good for you. That said all shoes need a few days to break in...a few minutes on then off at home watching TV for 3-4 days is a good trick.
I am yet to find any fully satisfactory cleaning/ deodorizing methods. If anyone has please post here!
