What’s the difference between single and double boots?

Single boots are lighter and more flexible — ideal for summer climbs on Mount Rainier or moderate alpine routes. Double boots add a removable liner for warmth and faster drying, making them the go-to choice for Denali, Aconcagua, and any expedition involving extreme cold or multi-day glacier travel.

How should mountaineering boots fit?

Your heel should stay locked in place, with room in the toe box to wiggle your toes on cold mornings. Too tight and you’ll lose circulation; too loose and you’ll get blisters. Try boots on with climbing socks and test them on an incline if possible — especially before a big climb.

Can I rent boots instead of buying?

Absolutely. Our double boot rental program is designed for climbers who want expedition-grade performance without the cost or commitment of ownership. Every pair is inspected, sanitized, and fitted by staff who work directly with RMI guides.
