I’m not sure but I believe you can ask for it to be done as part of a EG refurb.If you prefer to pay the shipping + insane rates of EG repairs, then I'd just go with them. If money is no option to you, it's best to have peace of mind.
EG might be able to do toe plates. I don't know. I've seen EG with toe plates, so...could be?
I just think it's personally a waste of time/money.
I’ve been to the EG factory and the people there were really helpful (not at all snooty either and much friendlier than the London shop in my experience). I’ve had a pair that had the uppers repaired with new leather due to damage + resole and the total was under £400 which I thought was quite reasonable. Although I agree as a general rule you do get charged a premium but that is true for most premium brands everywhere eg the cost of PP watch service or even Rolex.
