In reply to Eamonn:
Same thing happened to me with La Sportive Katanas after about a month - little rip just under the toes.
I approached them and the shop, but both said this is just something that can happen, especially with technical shoes that have v. thin soles, and not a design fault (hence no refund).
I was advised not to wear technical shoes at the wall, especially with modern bolt-on holds, as they will just shred sticky rubber.
Had the soles replaced at
