Between sizes is a very common question. The route 95% of customers
take is trying both to get a hands on feel of which size feels better
for them. Then return for a full refund or exchanging the one they’re
not happy with at no cost.

Trying one of each at the same time is best way to go because not only
is it much faster to figure out which pair fits you better, but you’re
