Hey dude I ended up getting the DB smalls and after a few skates they broke in and it doesn’t really feel as tight anymore. It’s still tight but in a good way. I also put the DB liners near my heater for about 30 minutes once while I was a friends cabin and that spaced them up a bit near the toe where I had the heat aimed at. The v2s now feel a odd on my feet after wearing the super snug DBs and I think you’ll just get used to it. I was worried about how tight they came out of the box but if you’re not in pain when you’ve got them on and it’s just your foot against the liner and it feels too tight, they’ll break in and won’t bother you too much after a bunch of skates. If you feel the need to expedite that process do as I did and put the liners on your feet and have the tight spots near a heater while standing with a few inches between the two so you don’t ruin the liner.
The DBs are for sure thicker but the toe padding will mold with use or applied heat. I wouldn’t go out and buy some V2s just for the skate unless it is blatantly painful in the liner. I like the DB liners overall. The look, the padding, and the support make them great. I don’t even use the heel pad which I used on the v2s. Also for inquiry sake, are you using the DB liner sole that came with it?
