Buy boots from Altberg up in Catterick. Most squaddies buy their own from here as they are very good cheaper boots that come in many configurations. Most lace to the toe so there is little need for 'breaking in'. Can't put in URL , advertising and all that!
Don't use talc before tabbing or running in boots as it absorbs moisture etc and forms lumps that give you more blisters. Use creams if you have to.
Use Anti-blister socks. More expensive but they work. Just done a week in the Pyrenees covering some 100Kms without a blister!!
Finally lace the boots fully and lock off the lower half of the boot by twisting the laces round each other a few times. Then lightly lace the upper half of the boot. This stops the lower part of the boot from allowing the foot to move about causing more blisters. The upper half needs to be loose to allow movement of the shin to prevent shin splints. Follow this advice for blister free runs!!
